Two bar magnets are placed side by side by side that the north pole of one magnet is next to the south pole of the other magnet. If these magnets are then pushed toward a coil of wire, would you expect an emf to be induced in the coil. Explain your answer.

Solution

Since both the magnets are aligned opposite to each other, so both the magnets will cancel out the effect due to each other while being pushed towards a coil. Let say, one magnet induces a clockwise emf in the coil, then the other magnet will induce anticlockwise emf in the coil and thus net emf induced in the coil is zero.
