A coil made of insulated copper wire is connected to a galvanometer. What will happen if a bar magnet is pushed into the coil ?

Question

A coil made of insulated copper wire is connected to a galvanometer- What will happen a bar magnet is kept close to the wire -

Toppr Admin · Accepted Answer

If the bar magnet is kept near the wire- and kept stationary- there is not change of flux through the wire- it remains constant-Hence emf induced in the solenoid according to-xA0-EMFinduced-x2212-d-x3D5-dt-0

A coil made of insulated copper wire is connected to a galvanometer. What will happen if a bar magnet is kept close to the wire ?

If the bar magnet is kept near the wire, and kept stationary, there is not change of flux through the wire, it remains constant.
Hence emf induced in the solenoid according to
$E M F_{i n d u c e d} = - \frac{d ϕ}{d t} = 0$
