Answer:

When a moving conductor(like copper or iron) placed in the magnetic field,then an emf is induced in an electrical conductor.
This is called electromagnetic induction.

Explanation:

Can we produce electricity by magnetic field?

In order to drive the current , an application of voltage(emf)
is compulsory. Without an application of voltage(emf),
there is no electricity.

Conclusion: In order to drive current,application of voltage is needy.

Where we get voltage?

How can we apply a moving force to very small electrons?

         There are number of methods  to produce voltage(emf).
An ****electromagnetic induction**** is one of the greatest method used 
to produce electricity.

Principle:
When a moving conductor(like copper or iron) placed in the magnetic field , then magnetic lines cuts the moving conductor.
If magnetic lines cuts the moving conductor ,
then emf(voltage) is induced in the conductor which further drives
the current when closed circuit is provided.

When a stationary conductor is placed in between moving magnets
, an emf is induced in the conductor.
