Electromagnetic Induction - Mutual Inductance due to Concentric Coplanar Circular Coils

In above figure we have two concentric coplanar coils (Primary coil of radius R and Secondary coil of radius r).Due to flux change in primary coil there will be a induced emf in secondary coil.

Magnetic field due to primary coil is 


flux change in secondary coil depends on current in primary coil



Mutual Inductance is shown below

Electromagnetic Induction - Mutual Induction

As we have variable source with increasing current in primary coil ,there will be a flux change in primary coil. Due to this flux change in primary coil there will be a flux change in secondary coil and this flux change in secondary coil will generate induced emf in secondary coil. This is called mutual induction. flux linked with secondary coil depends on current in primary coil ,so they are directly proportional to each other. differentiate with respect to time both sides   ------equation 1 As per faraday law induced emf in secondary coil is  ------equation 2 substitute value from equation 1 to equation 2   Visit PHYSICS page for more blogs
