Question

A flat coil enclosing an area of 0.29 m² is rotating at 56 rev/s, with its axis of rotation perpendicular to a 0.23 T magnetic field.

(a) If there are 1030 turns on the coil, what is the maximum voltage induced in the coil?
V
(b) When the maximum induced voltage occurs, what is the orientation of the coil with respect to the magnetic field?

The plane of the coil is at a 56° angle to the magnetic field.The plane of the coil is parallel to the magnetic field.    The plane of the coil is at a 37° angle to the magnetic field.The plane of the coil is perpendicular to the magnetic field.

Answer 1

vo The indused voltage in coil- { = NBA W Iw= angular frequeny - NBA anf here; No 1030 , B=0.23T, A = 0.29 m, f = 56 rev/s {= 103080:23 0 29 x 211856 VO ~ 24 173 volt i Max indused Itage = 24173 volt 162 Max Voltage occure when, B XÃ is maximum nie. BA sino is maxinomum że. O=90° ..so when plane of coil perpendicular to magnetic field Maximum voltage indused.
