Levi Martin · Answer 1

The correct answer is option C which is increasing the temperature of the conductor.

Explanation: When a coil or wire is moved around the magnetic field or magnetic field applied on conductor is changing, it will produce voltage in the conductor. The above phenomenon is known as the electromagnetic induction. It can be increased by increasing the number of turns of coil, or increasing the speed of conductor or increasing the strength of magnetic field. The increase in electromagnetic induction is not related to temperature. So option c is the correct option.

Answer

Increasing the temperature of the conductor

Explanation

Factors that affect the electromagnetic induction are increasing the number of turns on the winding, increasing the speed of the magnet and increasing the strength of the magnet. According to Faraday's law, the induced electromotive force across a conductor is equal to the rate at which the magnetic flux is cut by the conductor. In this phenomenon, EMF is generated from movement in the a magnetic field when the conducting wire "cuts" across the magnetic flux. The factor that affect the induced current are magnetic flux density, speed of cut and number of pieces of wire windings.
