What is the topic of the electromagnetic induction?

Electromagnetic Induction or Induction is a process in which a conductor is put in a particular position and magnetic field keeps varying or magnetic field is stationary and a conductor is moving. This produces a Voltage or EMF (Electromotive Force) across the electrical conductor.

What is electromagnetic induction class 10 CBSE?

The process of producing induced current in a closed circuit or in a coil by changing the magnetic field linked with the coil is known as electromagnetic induction. This process of producing induction current is known as electromagnetic induction.

What is the induced emf of induced current?

The induced emf (or current) always opposes the cause that produces it. Lenz’s law The induced emf of induced current is a circuit which always opposes the cause that produces it.

What is the direction of induced current in a magnetic field?

Ans. The wire is expanding to from a circle, which means that force is acting outwards on each part of the wire because of the magnetic field (acting in the downwards direction). The direction of the induced current should be such that it will produce magnetic field in upward direction (towards the reader).
