Physics Magnetism

When a wire is in a changing magnetic field, a current is induced in the wire this is called the 'Generator Effect'.

An example of using the Generator Effect is the water wheel; where water falls onto the wheel, which turns it. A Strong magnet is attatched to the rotation axis which changes the magnetic field around a coil of wire, inducing current.

Inverting current created by the Generator Effect: Can be achieved by Flipping the poles on the magnet used.

'Induced Magnetism' is the instance which a magnetic material gains its own magnetic fields, either 'Permanant' or 'Induced'.

Magnetic elements are the following: Cobalt (Co), Nickel (Ni), and Iron (Fe).

Only Steel, which is a compound of Iron, Carbon, Zinc, and many other elements, can keep it's magnetic fields 'Permanantly'. The other magnetic materials lose their magnetic fields, meaning it is 'Induced'.
