Why does it become more difficult to move a magnet towards a coil when the number of turns in the coil has been increased?

Solution:

When a coil has a large number of turns, the magnitude of induced e.m.f. increases, and the coil will oppose more according to Lenz’s law. As a result, moving a magnet towards a coil becomes more difficult.
