When there is a change in magnetic flux in a region there will be an EMF induced. And this EMF in turn produces an "induced current' when there is a resistor present. 

Induced current is the current produced by change in magnetic flux.

According to FARADAY'S LAW when there is change in magnetic flux over wire, then a current is is produced in the wire, such current is called induced current. Or producing current by induction.

We don't know about induced current , but the electricity which we are using is induced current.

A coil is placed in between magnets, when we rotate the coil, magnetic flux is changed and current is induced in coil, if we connect this coil to a small light, it will glows.

The elctricity that light used to glow is induced current.

The above concept is used in thermal power plants.

Those thermal power plants are responsible for current that we are using.

The concept of induced current is also used in transformers to convert high voltage current to low voltage current.

Hope you will understand

The above information is best of my knowledge.
