yes every magnetic field induces an emf in a loop of wire if it move on solanoid or it solanoid is move then only

The magnetic flux is a measure of the number of magnetic field lines passing through an area. If the magnetic flux through a coil is changed, a voltage will be produced.
This voltage is known as the induced emf.
If the flux changes. An emf will be induced. There are therefore three ways an emf can be induced in a loop of wire:
1. Change the magnetic field
2. Change the area of the loop
3. Change the angle between the field and the loop
