TERMS:

Faraday's Law

Any change in the magnetic environment of a coil of wire will cause a voltage (emf) to

be "induced" in the coil. No matter how the change is produced, the voltage will be generated.

The change could be produced by changing the magnetic field strength, moving a magnet

toward or away from the coil, moving the coil into or out of the magnetic field, rotating the coil

relative to the magnet, etc.

Electromotive Force

The electromotive force is the maximum potential difference between two electrodes of a

galvanic or voltaic cell. This quantity is related to the tendency for an element, a compound

or an ion to acquire (i.e. gain) or release (loss) electrons. For example, the maximum potential

between Zn and Cu of a well known cell.

Generator

Converts mechanical energy to electrical energy.

Charge

Electric charge is the physical property of matter that causes it to experience a force when close

to other electrically charged matter.

Magnetic Field

A magnetic field is a mathematical description of the magnetic influence of electric currents

and magnetic materials.

Lenz's Law

Lenz's law is a common way of understanding how electromagnetic circuits obey Newton's third law and

the conservation of energy.
