Polarization is the separation of the negative and positive charges within an atomic object, a nuclear, and a chemical system. Through induction, the movement of electrons within an object mixes. The system or the object is has an excess of the negative electrons concentrated on one side while the other side has a concentration of positive electrons. This leads to concentration of the opposite charges on different ends of the object (Askeland and Pradeep 116). This paper studies the misconceptions and the confusions regarding the magnetic and the electric polarization. For instance, there is a misconception that “a magnetic field exerts a force on both the steady and the moving objects” (Fernandez and Wai-Yim 344), this is not the case always. The other misconception is that “magnets attract all metals.” This assumption is also false
Polarization applies to both the electric charges and the magnetic charges. Not all metals are magnetic, different metals have a different orientation of the dipoles. A magnet attracts an object that has electrons flow in the same direction. However, not all metals have their negative and positive charges orientated in the same line (Wiedemann 467). This always cancels the magnetic field if the charges were to flow in the same direction. The effect of flow of electrons in different directions is the creation of a stronger field that causes no attraction to the magnets. Scientific evidence dismisses the general idea that all metals are magnetic.
Polarization applies in electric charges by dielectrics. These dielectrics are objects that cannot conduct electricity but an electric field polarizes them. This means that their electrons and protons have the ability to move freely in all directions (Fernande...

...c to have electric field around it. No more scientific evidence is required to put these assumptions in light. However, more researches on this subject are ongoing with numerous publishing of scholarly articles every day. Importantly, the articles lead to the same conclusion and without scientific explanation, polarization will remain difficult to many.

Magnets are everywhere! They are in telephones, computers, stereos, vacuum cleaners, refrigerators, washing machines, cars, compasses, TVs, VCRs, your doorbell and many other places. The earth itself is also a magnet. The Greeks discovered a mineral over 2,000 years ago that attracted things that were made of iron. This mineral was found in a part of Turkey that was called Magnesia, so they called it magnetite. A magnet is any material that attracts iron or things made of iron. All magnets have two poles, exert force on each other, and are surrounded by a magnetic field.
Magnetic materials are categorised as either hard or soft. A soft magnet material is easy to magnetise/demagnetise, whereas hard magnetic materials retain their magnetic properties after being magnetised. Permanent magnets are made up of hard magnetic materials which is able to create its own persistent magnetic field once magnetised. They can be made in different sizes and strength and thus, making them implantable into the body without anatomical restriction.

We have learned about atoms which have electrons and protons. The protons,electrons,and neutrons are the particles in an atom. The proton and neutron live in the nucleus and the electrons travel around the nucleus at very fast speeds. Atoms make up everything around us, even ourselves. Protons have a positive charge and electrons have a negative charge,while neutrons are neutral. The protons attract the electrons since they are opposites. Two similar particles repel while two different particles attract. We have also learned about magnets and magnetism. In order for an object to be magnetic it needs to be made out of iron and it’s domain need to be organized. The Earth has an internal magnet,but the poles are flipped so the North magnetic pole is in the South geographical pole. That is why compasses always point North. The opposite poles attract each other and the same poles repel each other. It is affected by distance so the farther away an object is from the magnet the weaker the magnet’s
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....
We charged the electroscope by induction by charging a rod and bringing it near the tip of the electroscope, touching the tip with one of our fingers while holding the charged rod next to the tip, and removing the rod. Since the rod does not touch the electroscope, polarization occurs. Our bodies can give and take electrons according to what the system needs. As we approach the electroscope with a positively charged rod, the system polarizes. The electrons rush to the tip of the electroscope, so that the top is negatively charged and the bottom is positively charged.
Since the charge density describes the distribution of negative charge in real space, it is a physically measurable quantity. Consequently, when used as a basis for the discussion of chemistry, the charge density allows for a direct physical picture and interpretation.
A magnet is any object that exhibits magnetic properties by attracting iron-containing objects and by creating a magnetic field. During 600 B.C. the Greeks were the first to use magnets when they encountered a mysterious stone that attracted iron and other similar material. Magnets attract ferrous objects such as iron, cobalt, nickel, and steel (How Magnets Work). Every magnet has a north and a south pole. The end that points to the North is called the North Pole while the pole that points South is called the South Pole. Opposite poles attract each other. Therefore, the North Pole of a magnet will attract to the South Pole of another magnet. On another note, same poles repel each other. Therefore, two North Poles will repel each other (Reis).
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...
Most objects are made of matter with equal amounts of positive and negative charge. Objects with the same # of positive and negative charges are electrically balanced, or neutral. Electric force is observed only when the balance of charge on objects is disturbed.
Throughout the past century, investigations of quantum and particle physics phenomena have proven to show the most significant concepts and ideas in the physical and sub-atomic world. However, the discoveries yet to be made are endless. One of the most fascinating concepts in the sub-atomic universe is the idea of spintronics. Spintronics is the quantum study of the independent angular momentum (not to be confused with the orbital angular momentum of the electron) of a particle, typically that of an electron (Introduction). An electron is a fundamental particle, with a negative charge, and is independently studied in the process of spintronic devices. The spin angular momentum of electrons is ±½ћ.

Temperature has a large effect on particles. Heat makes particles energized causing them to spread out and bounce around. Inversely the cold causes particles to clump together and become denser. These changes greatly F magnetic the state of substances and can also influence the strength of magnetic fields. This is because it can alter the flow of electrons through the magnet.
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
A magnet has an invisible field that forces other objects to respond to its properties. This powerful force, which is referred to as the magnetic field, has particles called electrons that actively shift and move within the field. These electrons constantly revolve around the poles, thereby creating energy that attracts objects. Because of this, a magnet has the ability to draw objects towards itself. This ability, which is called magnetism, is caused by the force field that magnets create through its protons (positive charge) and electrons (negative charge).
