Question

What is the SI unit of magnetic induction?

Answer 1

Magnetic induction:

1. Magnetic induction, also called electromagnetic induction refers to the production of voltage (or EMF) across an electrical conductor placed inside a varying magnetic field. According to Faraday’s law, for a closed circuit, the induced electromotive force is equal to the rate of change of the magnetic flux enclosed by the circuit.
2. Electromagnetic Induction is defined as the process in which a conductor is kept in a varying magnetic field or field that is stationary and the conductor is moving. This produces electromotive force in the electric conductor
3. This phenomenon was discovered by Michael Faraday in 1830.

An illustrative diagram of electromagnetic induction is shown below.

4. The SI unit of magnetic induction is Tesla $\left(\mathrm{T}\right)$.

5. The dimension of magnetic induction is $[{\mathrm{M}}^1{\mathrm{T}}^{-2}{\mathrm{I}}^{-1}]$.
