There is a close relationship between magnetic forces and the generation of electric current. Explain how magnets can be used to generate electric current and how electric current can be used to create electromagnets. For each, give an example of a device you would find around the home.

Inside a generator is a magnet, some electrical wire, and a source of mechanical energy. The mechanical energy moves the wire into the magnetic field of the magnet so that the wire cuts through the magnetic lines of force. As a result, electric current is produced. Electric generators can come in all sizes

Answer:

If a magnet is continuously moved to and fro in a coil or vise versa , due to change in magnetic field passes through a coil , electric current can be produced, it called electromagnetic induction.

And if current flows in a coil , it will behave like a magnet , that is called Electromagnetism.

Explanation:

What is electromagnetic induction and Electromagnetism ?

According to the Faraday's law , when magnetic field passing through a coil is changed , an electric potential is developed , that causes current , the phenomenon is called Electromagnetic induction.
In it ,the induced emf (potential)is directly proportional to the rate of change of magnetic flux,
[tex]e = N. \frac{(B.A)}{dt}[/tex]
Example- Generator.
According to the Clock wise rule , when current flows in a coil , according to the direction of current , its one face become N pole and S pole, thus it becomes a magnet or tiny magnet .
Example- Solenoid.

Hence Electromagnetic induction and electromagnetism can be defined.
