Question

A metallic loop is placed in a non uniform magnetic field..so will emf will induce

Answer 1

For induced emf to develop in a coil, the magnetic flux through it must change.

But in this case, the number of magnetic lines of force through, the coil is not changing.

Therefore emf will not induce.

Explanation: No, because Farraday's first law states that, whenever there is a change in amagnetic flux associated in a closed loop takes place an emf is induced in the wire.. i.e. e= - (change in flux) / (change in time).
