Acoil of wire (61.163 cm^2 area) can generate a voltage difference when rotated in a magnetic field. if a 904 turn coil is rotated at 65 hz in a b field of 0.001 t, what is the voltage created ?

Explanation:

As we know that the rotating coil will have change in the angle with time at all instant of time

so at any general instant of time we can say

now we have

so we have

so we have maximum induced EMF in the coil is given as

N = 904 turns

B = 0.001 T

f = 65 Hz

now we have

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

im sorry i dont know
