Electromagnetic


Research
Electromagnetic is the form of energy that spans over electricity and magnets. This includes electromagnets, a magnet made using electricity. Electromagnetism is one of the five forms of energy. These five forms being mechanical, electromagnetic, thermal, chemical, and nuclear. Magnets work like the following. They each have two poles, north and south. The north pole of a magnet will attract the south pole of another magnet. The south pole of a magnet will attract the north pole of another magnet. The south pole of a magnet will repel the south pole of another magnet. The north pole of a magnet will repel the north pole of another magnet.

Application
A simple motor works like the following. There is a battery in a plastic case with a magnet on top. When the coil of wire becomes part of the circuit, it becomes an electromagnet. One side of this is positive and the other negative. When the wire starts spinning one of the poles attracts to the magnet and the other one repels. This keeps it going and so does the force of momentum and inertia. This is how the world’s simplest motor works.

Experiment
The purpose of the experiment was to test the radiometers functionality. The flashlight was shone on the black vanes of the radiometer to test the affects. Then the light was shone on the white vanes on the opposite side of the radiometer to test the affects. When no light was being shone on the radiometer vanes, it did not spin, rotate, or move in any way. It was completely still unless a force acted on it. When the light was shone on the black vanes, applying an electromagnetic force, it rotated the radiometer in the direction that the light was shining, and it also shook up and down a little. When light was shone on the white vanes, not applying an electromagnetic force, nothing happened to the position of the radiometer within the glass bulb. It did not rotate, shake, or turn around in any way within the glass bulb.
