Electromagnetism Experiment
Introduction:
=============
I start the introduction with a question: Will increasing current in
an electromagnet increase the power of the electromagnet?
The electromagnet we will be making is a very primitive one compared
to that of the complexity of modern electromagnets found in machinery,
but the way it works is almost identical. Electromagnetic technology
is extremely complex and because it is an electromagnet, the higher
the current, the stronger it becomes, and with this an electromagnet
can become incomprehensively strong. Such an example is that used in
theme park rides to stop moving parts etc. these electromagnets are in
fact so strong that when uncovered, if you were to stand with a
spanner in your hand 10 metres away, it would pull the spanner out of
your hand along with the rest of your arm! To understand fully how an
electromagnet works read on…
Background information:
When an insulated wire is wrapped around some form of iron, nickel or
cobalt core, whether it be a nail or a u-shaped core, and then
attached to a power supply it creates an electromagnet capable of
picking anything from the size of a paperclip right up to anything as
big as a car and bigger! Obviously such a primitive electromagnet
would not be able to lift a car but a more advanced one would have no
problem lifting a car. When the power supply is cut off the items
picked up will fall off. This is because the current creates a
magnetic field and this magnetic field is lost when it is turned off.
When a current channels through an electromagnet a magnetic field is
produced. This field is built up in a series of concentric rings. The
diagram below shows a cross-section of a wire's magnetic field. As you
come further away from the wire the field weakens and spreads further
apart from each ring.

There are four main factors that affect the strength and size of this

Levittown project was taken up in the U.S. after the end of Second World War, with the aim of providing mass housing facilities to people in the wake of increasing urbanization and problems of accommodating large population in limited urban area (Friedman. 1995). The first of Levittown apartments were constructed on Long Island, New York and they symbolized the modern trends of urbanization and housing developments (Clapson. 2003). This paper shall study the impact of Levittown project on trends of further urbanization and analyze the aesthetics of design and development involved in it.
In the short story “Cornet at night” by Sinclair Ross, Tom Dickson is a young farm boy who lives on a farm with his parents. He is very naive and has not had a chance to experience the outside world for his own. He knows only what he learns from the farm and school, but now that he gets to go on a small adventure on his on, he grows up in a variety of ways. One way in which Tom grows up is when he goes to town by himself. He has gone before, but with the security of his parents with him, and for a young boy to go to another town “eight miles north of here” is a large task for such a young boy, thus showing one way that he matures. To illustrate this, as Tom rolls into town with Rock he says, “I remember nothing but a smug satisfaction with myself, an exhilarating conviction of importance and

With regard to constructing the “Elevator Car”, or climber mechanism, many ideas have been tossed around N.A.S.A. in the last 5 years. In addition, Space Forward challenged the world by asking private organizations to build there own mechanism and promised the wining team 4 million dollars for there work. As a result, the Space Elevator challenge began and th...
In the beginning, you need to move your car to a safe area. It is very dangerous to jack a car up on uneven ground because there is a chance that your car could roll over. “Stop the car on a level stop, it is unsafe to jack up a car on an incline.” First, you need to jack the car up. To do this, you take the jack from the truck of your car, place it in the designated area under your car, and turn the bar protruding from it until
Over the third quarter of physical science we have discussed heat, energy, electricity and magnetism. I have decided to do my paper over these four topics. If you have any questions please hold them till the end.
How do you build a vehicle capable of climbing a tether into space, under its own power? This leads to another
After doing a short research i have enlisted these items which is excellent in performances and will be your first choice in the purpose of lifting your vehicles or automobiles and you will be completely satisfied after using these product which i mentioned below in details for you.
Lift kits on trucks change the angle of the driveshaft and can cause U-joint and powertrain issues. Slamming a vehicle drastically changes the alignment angles causing the automobile to wear out tires quickly. Another difference between suspension modifications and the upgrades mentioned above is the amount of work involved in returning it to a factory original condition.
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.
The Earth’s magnetic field is a major component to exploring the earth. The north and the south poles have always been a guide for travelers. Using compasses, the direction of the north pole and the south pole has always been provided by the magnetic force of the magnetic field. What many people do not know though is the earth’s magnetic field provides way more than that. The magnetic field, also known as the magnetosphere, protects us from all kinds of harmful substances. Some of these substances include solar wind and harmful radiation from the sun. The magnetosphere also protects the atmosphere, which protects us.
