Question

A 60 turn, 10.0 cm diameter coil rotates at an angular velocity of 8.00 rad/s in a 1.20 T field, starting with the normal of the plane of the coil perpendicular to the field. Assume that the positive max emf is reached first. (a) What (in V) is the peak emf? b) At what time is the peak emf first reached?

(c) At what time is the emf first at its most negative?

(d) What is the period of the AC voltage output?

Answer:4.52389342117 V

0.196349540849 s

0.589048622548 s

0.785398163397 s

Explanation:B = Magnetic field = 1.2 T

A = Area =

d = Diamter = 10 cm

N = Number of turns = 60 turn

= Angular velocity = 8 rad/s

Peak EMF is given by

Peak EMF is 4.52389342117 VTime is given by (maximum)

Peak EMF is reached in 0.196349540849 sNegative case

The time taken is 0.589048622548 sFor output voltage

Time taken is 0.785398163397 s
