electromagnetic induction i.e currents can be induced in coils (Select the best)A.Only if the coil movesB.Only if the coil moves and magnet also moves in the same directionC.if relative motion of coil and magnet is present.D.Only if the magnet moves

The phenomenon due to which there is an induced current in one coil due to current in a neighboring coil is __________________.(1 Point)electromagnetism.alternating current.self-induction.mutual induction.

When a coil is placed in a constant external magnetic field directed perpendicular to the plane of the coil, which of the following actions does not induce an emf in the coil?*1 pointCollapsing the coil.Changing the strength of the magnetic field.Moving the coil through the field without changing its orientation with respect to the field.Rotating the coil.

All the following devices depend on electromagnetic induction in their operation, except... a) The electric transformer in chargers b) The electric generator at power plants c) The electric motor in toys d) The metal detectors that people walk through at airports.

What are electromagnetic inductions

A circular coil lies flat on a horizontal table. A bar magnet is held above its centre with its north pole pointing down. The stationary magnet induces (when viewed from above)Group of answer choicesno current in the coil.a clockwise current in the coil.a counterclockwise current in the coil.a current whose direction cannot be determined from the information given.
