The induced current is the highest when the direction of motion of the coil is at right angles to the magnetic field.
- The induced current is proportional to the time change in magnetic flux.
- According to Faraday’s law of electromagnetic induction, when there is a change in flux, an emf and current are induced in the coil, and this current will create its own magnetic field.
- The direction of the current can be determined by considering Lenz’s law, which says that an induced electric current will flow in such a way that it generates a magnetic field that opposes the change in the field that generated it.
- If the applied magnetic field increases, the current in the wire will flow so that the magnetic field that it generates around the wire will decrease the applied magnetic field.
