An electric generator contains a coil of 125 turns of wire, each forming a rectangular loop 45.0 cm by 20.0 cm. The coil is placed entirely in a uniform magnetic field with magnitude B = 3.50 T and with B-> initially perpendicular to the coil's plane. What is the maximum value of the emf produced when the coil is spun at 1250 rev/min about an axis perpendicular to B->?

Answer #1

When the loop is rotate with an angular speed then the magnetic flux with respect to time is given as:

We take cosine because at t=0 flux through loop is maximum

Now, ew know that

Therefore, maximum induced emf is given as:

0 0
