What is the magnitude of the emf induced in the coil

Reference no: EM13973433

1.A circular coil with 50 turns of wire has a diameter of 6.00 cm. The total resistance of the coil is 0.450 ?. An applied uniform magnetic field is directed upward, perpendicular to the plane of the coil.

a) If the magnetic field changes linearly from 0.000 T to 0.500 T in 0.800 s, what is the induced emf in the coil while the field is changing?

b) What is the magnitude and direction of the induced current in the coil while the magnetic field is changing?

2. A horizontal 100-turn rectangular coil is located in a uniform magnetic field of magnitude 0.900 T directed upward perpendicular to the plane of the coil. If the area of the coil increases linearly at the rate of 8.00 x 10-3 m2/s, what is the magnitude of the emf induced in the coil? If the resistance of the coil is 4.00 ?, what is the magnitude and direction of the current induced in the coil?

Please post with formulas used :)
