In this day and age with oil prices rising and the recession hitting everyone, more people are looking for more ways to save on cost of the most used items. Electricity is the most common and used item people use in everyday life, but what they do not know is that there is a simpler way to produce electricity with magnets. How do magnets produce electricity? Why not use magnets to produce all electricity? These questions are common in people that research different avenues to provide electricity without having to spend a fortune on other renewable energy sources. Magnets and all their uniqueness is the key to the future discoveries and creation of new machines that produce electricity without using fossil fuels.
Magnets have unique characteristics unlike other metals. The best suited metals for magnets are iron, cobalt, nickel, or mixtures of the metals like steel. Magnets come in all different shapes and sizes, but the typical shapes are the straight or horseshoe magnets. The unique characteristic of magnets is that it has a north and south pole just like Earth. The poles on a magnet can be located on many different positions on the magnet itself as long as one side is north and the other side is south. The magnet’s poles are the reasons why magnets can produce electricity. Magnets are used in all types of electrical applications and without magnets the technology that people take for granted would not be possible. “Magnets are essential for the generation of electric power and are used in motors, generators …” (Magnet).
However, understanding magnets at the atomic level will give the source to why magnets have a south and north pole. The electrons of an atom are similar in all atoms for they spin or rotate as they move around ...

...ield, sending a shock wave of magnetic energy down to the surface, creating a way to harness electricity from the planet. Taking into consideration that in theory electricity can come from the magnetic field around Earth, no devices have been developed to show that this device actually works in this day and time.
Magnets have magnetic fields that create electricity with rotations because the electrons in magnets move in one direction. Knowing that magnets generate electricity with rotation; magnets need to be examined fully to understand all the potential magnets have to offer us in the electrical energy field. With technology growing by leaps and bounds new devices and ways to create electricity can be developed if, and only if, magnets are the essence of the technology. Magnets hold the key to solving and developing future devices that can generate electricity.

Magnetic bearings have provided us with new ways and innovations to run various systems such as space equipment and energy storage systems. Magnetic bearings have given people a way to run systems unlike any other bearing system. They have implemented a lubrication free and maintenance free system, which in turn provides a much cheaper and unblemished system. Although magnetic bearings are not perfect and are limited in specific areas, we believe they have the potential to revolutionize the field of mechanical power transmission.
All magnets in nature are dipoles, that is, magnets having both a north and south pole (Gibney). If a bar magnet is broken into two pieces, each piece becomes a dipole (Gibney). Yet somehow, both positive and negative charges, exist separately (Gibney). However, a monopole would only have one pole, either a north or a south, not unlike a normal electric charge (Gibney). Monopoles do not occur normally. However, some scientists believe they could be synthesized. This is an exciting possibility because of the dramatic implication.
Rauen (2016) wrote that certification demonstrates that the nurse has the knowledge and skills beyond the basics in the specialty area. The patient, physician, and nurses expect a higher standard when a nurse works in a dedicated field. When a nurse is working in a focused field, more knowledge needs to be obtained to understand the nature and complexity of the disease. The professional certification shows others that there is acknowledgment of quality of care. As hospitals and nurses become more competitive, this standard is raised and consequently a higher quality of care is expected. And, one way of designating high quality of care is through certifications. Professional certification is recognized by American Nurses Credential Center’s (ANCC’s) Magnet Recognition Program for excellence in nursing services. According to the ANCCs (2017), The Magnet Recognition Program’s goals and guiding principles are to promote quality, identify excellence and disseminate best practices. With a hospital having a Magnet status, this will attract and retain top nurses, improve patient care, foster a collaborative culture, and advance nursing standards and practice.
A magnetar is a kind of neutron star with one of the strongest magnetic fields detected in the Universe. Many stars have magnetic fields, but that by itself does not distinguish as magnetar from other stars. The distinguishing characteristic of magnetars is their extraordinarily intense magnetic fields that range between ~1014 and ~1015 Gauss (G) making them hundreds to thousands of times stronger than pulsars and among the strongest magnetic fields ever observed (Tiengo & Schartel, 2013). Explained another way ~1015 is equal to ~1011 tesla; or a magnetic field so strong that if the Moon possessed that magnetic field, the magnetic stripe on all credit cards would be stripped clean (Tate, 2010). That still might be challenging to comprehend. However, the strongest permanent magnet on Earth is approximately 1 Tesla compared to a magnetar with at least 100 billion times that strength (Tate, 2010).
The relationship between electricity and magnetism is that each phenomenon generates a field. Electric fields can be pictured by thinking in terms of gravitational forces. Where, any two objects have a gravitational force on one another. Any two electric charges have a force between them (either repelling, or attracting depending on polarity). These electric fields are vector forces, with size and direction at each point in space....
Electromagnets are created by having an iron core wound with a conductor carrying current. The strength of the electromagnet depends upon the amount of current passing through the conductor. Also the current can be easily stopped and started to form an electromagnet and de-energize respectively as per the need of the work to be performed.
The phenomenon called electromagnetic induction was first noticed and investigated by Michael Faraday, in 1831. Electromagnetic induction is the production of an electromotive force (emf) in a conductor as a result of a changing magnetic field about the conductor and is a very important concept. Faraday discovered that, whenever the magnetic field about an electromagnet was made to grow and collapse by closing and opening the electric circuit of which it was a part, an electric current could be detected in a separate conductor nearby. Faraday also investigated the possibility that a current could be produced by a magnetic field being placed near a coiled wire. Just placing the magnet near the wire could not produce a current. Faraday discovered that a current could be produced in this situation only if the magnet had some velocity. The magnet could be moved in either a positive or negative direction but had to be in motion to produce any current in the wire. The current in the coil is called an induced current, because the current is brought about (or “induced”) by a changing magnetic field (Cutnell and Johnson 705). The induced current is sustained by an emf. Since a source of emf is always needed to produce a current, the coil itself behaves as if it were a source of emf. The emf is known as an induced emf. Thus, a changing magnetic field induces an emf in the coil, and the emf leads to an induced current (705). He also found that moving a conductor near a stationary permanent magnet caused a current to flow in the wire as long as it was moving as in the magnet and coiled wire set-up.
The mechanical energy (torque) is produced when opposing magnetic fields try to lineup. Therefore, the center line of the north pole of a magnetic field is directly opposite to the centerline of the south pole of another magnetic field (Fitzgerald et al., 1981). The opposing magnetic fields in a motor are generated by two separate concentrically oriented components, the stator and a rotor (Figure 2-5). Figure 2 5 Rotor and stator schematics of a three-phase DC motor. The stator is the stationary component, while the rotor is the rotational component of the motor.
At the surface of the earth, the pole of this equivalent bar magnet, nearest the north geographical pole is actually a south” magnetic pole. This paradoxical situation exists since by convention a north seeking end of a compass needle is defined as pointing north yet must point to a pole of opposite sense or South Pole of the earth’s magnetic field. The flux lines of the field exhibit the usually pattern common to a small magnet as shown below in fig 1.
The Earth is a home for mankind, a planet sustaining life, and it is also a giant magnet! Magnets in general, no matter what type of magnet it is, have two end faces called poles. Poles are where the magnetic force is most effective. These two poles are known as the north pole and the south pole. Magnets also create a magnetic field from the particles within the magnet. The Earth resembles this same structure. The earth has a geographic north pole and a geographic south pole. Since opposites attract in magnets the south pole of the core of the earth points towards the geographic north pole of the earth and the north pole points towards the geographic south pole of the earth. The core of the earth serves the same purpose as the particles in m...
In 1831, using his "induction ring", Faraday made one of his greatest discoveries - electromagnetic induction: the "induction" or generation of electricity in a wire by means of the electromagnetic effect of a current in another wire. The induction ring was the first electric transformer. In a second series of experiments in September he discovered magneto-electric induction: the production of a steady electric current. To do this, Faraday attached two wires through a sliding contact to a copper disc. By rotating the disc between the poles of a horseshoe magnet he obtained a continuous direct current. This was the first generator. From his experiments came devices that led to the modern electric motor, generator and transformer.
The first time we know about magnets was in 1269, when a soldier named Peter Peregrinus, wrote a letter about everything that was known at that time about a stone called magnetite. It is reported that he was writing this when he was guarding the walls of Lucera, a small town in Italy. It is also reported that, “While people insi...
Electric currents produce magnetic fields, they can be as small as macroscopic currents in wires, or microscopic currents in atomic orbits caused by electrons. The magnetic field B is described in terms of force on a moving charge in the Lorentz force law. The relationship of magnetic field and charges leads to many practical applications. Magnetic field sources are dipolar in nature, with a north and south magnetic pole. The magnetic field SI unit is the Tesla, it can be seen in the magnetic part of the Lorentz force law F magnetic = qvB composed of (Newton x second)/(Coulomb x meter). The smaller magnetic field unit is the
Magnetic anisotropy is defined as the directional dependence of the magnetic properties for materials. Strong easy-axis anisotropy is a prerequisite for hard magnetism while near-zero anisotropy is desirable for soft magnets. Generally, the tendency for magnetization to lie along an easy axis is represented by the energy density
