What will happen when a magnet is taken towards a circular coil?

Dear Student, 
Please find below the solution to the asked query: 

• According to Lenz's law, when a closed coil is linked with a varying magnetic flux, then some current is induced in the coil.
• So, when a magnet is taken towards a circular coil, then a varying magnetic flux is linked with the coil so that current is induced in the coil. This phenomenon is said to be electromagnetic induction.

Hope this information will clear your doubts about  Electromagnetic induction.
