A44-turn rectangular coil with length ℓ = 17.0 cm and width w = 8.10 cm is in a region with its axis initially aligned to a horizontally directed uniform magnetic field of 765 mt and set to rotate about a vertical axis with an angular speed of 64.0 rad/s.
(a) what is the maximum induced emf in the rotating coil?
(b) what is the induced emf in the rotating coil at t = 1.00 s?
(c) what is the maximum rate of change of the magnetic flux through the rotating coil?

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
