Question

What do you mean by electromagnetic induction? In what way can the magnitude of the induced current be increased? State the rule which gives the direction of the induced current

Answer 1

Answer:

1. Faraday's Law of Induction

Explanation:

1. In other words, Electromagnetic Induction is the process of using magnetic fields to produce voltage, and in a closed circuit, a current. So how much voltage (emf) can be induced into the coil using just magnetism.

Answer:

2. The magnitude of the induced current can be increased by: Taking the conductor in the form of a coil of many turns of insulated wire.

Explanation:

2. Increasing the strength of the magnetic field used.

Answer:

3. Fleming's right-hand rule (for generators) shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field.

Explanation:

3. It can be used to determine the direction of current in a generator's windings.
