A circular insulated copper wire loop is twisted to form two loops of area
A circular insulated copper wire loop is twisted to form two loops of area
Updated On: Jun 14, 2022
- The emf induced in the loop is proportional to the sum of the areas of the two loops
- The amplitude of the maximum net emf induced due to both the loops is equal to the amplitude of maximum emf induced in the smaller loop alone
- The net emf induced due to both the loops is proportional to $\cos \omega t$
- The rate of change of the flux is maximum when the plane of the loops is perpendicular to plane of the paper

Concepts Used:
Electromagnetic Induction
Electromagnetic Induction is a current produced by the voltage production due to a changing magnetic field. This happens in one of the two conditions:-
- When we place the conductor in a changing magnetic field.
- When the conductor constantly moves in a stationary field.
Formula:
The electromagnetic induction is mathematically represented as:-
e=N × d∅.dt
Where
- e = induced voltage
- N = number of turns in the coil
- Φ = Magnetic flux (This is the amount of magnetic field present on the surface)
- t = time
