the induced emf
E = -dF/dt = -B * d(A * cos(q(t)) / dt
E = B * A * sin(q) * dq / dt
then
8 deg = 0.10472rad
then
dq/dt = 0.10472 / 0.3
dq/dt = 0.349 rad/sec
after this A = N * pie * r^2
A = 20 * 3.14 * (6 * 10^-3 / 2)
A = 5.65 * 10^-4 m^2
then by all the values in the formula
F = 0.8 * 5.65 * 10^-4 * 0.349 * sin(6 deg)
F = 1.64 * 10^-5 V
so the induced emf in the coil is 1.64 * 10^-5V
Can someone help me? Thank you. Problem 25.62 Part A Experiments to study vision often need...
Experiments to study vision often need to track the movements of a subject's eye. One way of doing so is to have the subject sit in a magnetic field while wearing special contact lenses with a coil of very fine wire circling the edge. A current is induced in the coil each time the subject rotates his eye. Consider the experiment shown in the figure in which a 15-turn, 6.0-mm-diameter coil of wire circles the subject's cornea while a 1.0T...
