A25-turn circular coil of wire has diameter 1.00 m. it is placed with its axis along the direction of the earth’s magnetic field of 50.0 μt and then in 0.200 s is flipped 180°. an average emf of what magnitude is generated in the coil?

The magnitude of average emf is 9.813 mV.

Explanation:

Given that,

Number of turns = 25 turns

Diameter = 1.00 m

Magnetic field = 50.0μm

Time = 0.200 s

Angle = 180°

We need to calculate the area of the coil

Using formula of area

We need to calculate the average emf

Using formula of emf

Where, N = number of turns

A = Area

B = magnetic field

Put the value into the formula

Hence, The magnitude of average emf is 9.813 mV.
