Arectangular coil with sides 0.150 m by 0.250 m has 487 turns of wire. it is rotated about its long axis in a magnetic field of 0.570 t. at what frequency, in complete cycles per second, must the coil be rotated for it to generate a maximum voltage of 115 v?

Frequency is 1.758 Hz

Solution:

As per the question:

No.of turns, n = 487 turns

Magnetic field, B = 0.570 T

Area of the field, A =

Maximum Voltage,

Now,

To calculate the frequency:

Angular frequency,

Maximum emf,

Maximum emf,

d

explanation:

v=uf/(u-f)
