A circular loop which possesses 55 turns is placed in a uniformmagnetic field. The direction of the magnetic field makes an angleof 70 o with respect to the normal direction to the loop. Themagnetic field strength B is increased at a constant rate from B1=3T to B2 =17T in a time interval of 20 s. If Ф1 is 3.99 Wb,
a) What is the radius of the wire? (PLEASE THOROUGHLYEXPLAIN)
b) What is the EMF?
c) What is the current if the electrical resistance of the loopis 7 ohms?
