CBSE Class 10 Answered

in fardays experiment if instead of moving the magnet towards the coil we move the coil towards the magnet , will there be any induced current ? justify your answer . compare the two cases

The electromagnetic induction occurs due to the change in the magnetic field. 

The different ways to induce current in a coil are as follows:

1. Induce current on a coil by moving the coil in a magnetic field.

2. Induce current on a coil by changing the  magnetic field across it.

3. If a coil is moved rapidly between the two poles of a horse-shoe magnet, then an electric current is induced in the coil. 

 
We can compare these two cases by checking it with the deflection brought about in the galvanometer.
In both the cases the deflection in the needle of the galvanometer will take place due to the induced current caused by the change in the magnetic field.
