Answer:
When the magnetic flux ceases, then the induced current decreases to zero and finally vanishes up.
Explanation:
An EMF is just another force, like pushing your hand against a brick wall.
The collapsing magnetic field is like the hand above, it is doing the pushing. The force against the wall is called mechanical pressure and the force against the electrons is called EMF.
If you stop pushing on the wall the mechanical force you were creating ceases to exist.
Like wise when the magnetic field’s rate of change passes through zero as it changes direction it generates no force on the electrons.
If the electrons are moving ceasing the EMF would leave them drifting at the same speed and direction until acted on by another force.
That other force may be an EMF starting to build in the opposite direction, room temperature resistance or the emission of radio waves or even x-rays (emitters are loads too). Either way the electrons very quickly stop.
