A square loop, 5 cm on a side, is placed within a 3.7 T magnetic field such that the field makes an angle of 60( to the loop. Calculate the magnetic flux through the loop. 

The loop in question # 1 is rotated to that it is parallel to the magnetic field. If this takes 0.1 seconds, find the voltage induced in the loop. 

The magnetic flux through a coil containing 50 loops changes from 30 Wb to ?30 Wb in 0.42 seconds. What is the voltage induced in the coil? 

A square coil, 6.5 cm on a side, consists of 275 loops. If the magnetic field is perpendicular to the loop, find the voltage induced if the field changes from 2.0 T to 0.5 T in 0.05 seconds.
