Question

What is i1, the induced current in the loop at time t = 0.675 s? i1 is defined to be positive if it flows in the negative y-direction in the segment of length h?

Answer 1

A conducting wire formed in the shape of a right triangle with base b = 31 cm and height h = 58 cm and having resistance R = 2.3 Ω, rotates uniformly around the y-axis in the direction indicated by the arrow (clockwise as viewed from above (loooking down in the negative y-direction)). The triangle makes one complete rotaion in time t = T = 1.8 seconds. A constant magnetic field B = 1.3 T pointing in the positive z-direction (out of the screen) exists in the region where the wire is rotating.
