Alternating current
... Direct current (DC) is electric current that is always flows in one direction. A battery produces a direct current. Alternating current (AC) is electric current that reverses direction in a regular pattern. When you plug your CD player or any other appliance into a wall outlet, you are using alterna ...

MAGNETISM
... Magnets exert forces on one another. They are similar to electric charges, for they can both attract and repel without touching, depending on which end is held near the other. Also, like electric charges, the strength of their interaction depends on the distance of separation of the two magnets. Whe ...

Exploring the Magnetic Field of a Slinky
... 14. Once you get a good display of current on the bottom, and induced emf on the top, make an accurate sketch of the scope display. Make sure to write down all relevant parameters such as the time scale and the voltage scales of both channels. Also record the area of the loop and the number of turn ...
