Frequently Asked Question:
What is the magnitude of the average emf EE induced as the coil is rotated?
When a coil rotates in a magnetic field an emf is induced, and when the coil starts its motion from the position at which its plane is parallel to the field lines, and then it rotates by 180 degrees, the average induced emf in it is zero.
How do you find the magnitude of an induced emf?
To find the magnitude of EMF induced along the moving rod, we use Faraday’s law of induction without the sign: EMF=NΔΦΔt EMF = N Δ Φ Δ t . In this equation, N=1 and the flux Φ=BAcosθ.
What is the magnitude of the emf induced in the rod?
An emf induced by motion relative to a magnetic field is called a motional emf. This is represented by the equation emf = LvB, where L is length of the object moving at speed v relative to the strength of the magnetic field B.

What is the total magnetic flux?
Magnetic flux is a measurement of the total magnetic field which passes through a given area. It is a useful tool for helping describe the effects of the magnetic force on something occupying a given area. The measurement of magnetic flux is tied to the particular area chosen.
