What conditions are required to induce a current in a loop of wire?
There are three conditions required to induce a current in a loop of wire:
1. A change in magnetic field: The loop of wire must be placed in a changing magnetic field. This can be achieved by moving the magnet towards or away from the loop, or by changing the strength of the magnetic field.
2. Motion of the loop: The loop of wire must be in motion with respect to the magnetic field. This movement can be either rotational or translational.
3. Orientation of the loop: The loop of wire must be oriented such that the magnetic field lines pass through the loop at an angle. This angle between the magnetic field and the loop is known as the angle of incidence.
