's magnetic field. The magnetic field of the earth at the location of the coil is 5 x 10^-5 T. If the coil is rotated about an axis perpendicular to its plane with an angular velocity of 50 rad/s, find the maximum emf induced in the coil.
We can use the formula for the emf induced in a rotating coil:
emf = NBAω
where N is the number of turns, B is the magnetic field, A is the area of the coil, and ω is the angular velocity.
The area of the coil is πr^2 = 3.14 x (0.12 m)^2 = 0.045 m^2.
Substituting the given values, we get:
emf = (10)(5 x 10^-5 T)(0.045 m^2)(50 rad/s) = 0.113 V
Therefore, the maximum emf induced in the coil is 0.113 V.
