Electromagnet
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil.
electric ------> magnet
3
Electromagnet is a temporary magnet.
The temporary means the magnet field will appear, if a current flows through the coil.

Electromagnet
The magnetic field will stronger if:
The electric current increase.
The number of turn of coil increase.
The magnetic field of electromagnet is also depend on the core.
If we put the iron (magnetic material) inside the core the electromagnet will stonger than we left the core with only the air.

Electric generator
We can produce the electricity by rotating electric conductor between two magnets.
The electricity will greater if :
- we replace the stronger magnet.
- we rotate the conductor in faster rotation.
