Acoil of 1,000 turns encloses an area of 85 cm^2. it is rotated in 0.090 s from a position where its plane is perpendicular to earth's magnetic field to one where its plane is parallel to the field. if the strength of the field is 6.0 x 10^-5 t, what is the average emf induced in the coil (in mv)?

The average emf induced in the coil is .

Explanation:

Given that,

Number of turns = 1000 turns

Area = 85 cm²

Time = 0.090 s

Its plane is perpendicular to Earth's magnetic field.

Angle = 0°

Magnetic strength

We need to calculate the magnetic flux

Using formula of magnetic flux

Put the value into the formula

We need to calculate the average emf induced in the coil

Put the value into the formula

Hence, The average emf induced in the coil is .

car a and b are moving in opposite directions
