A conducting wire formed in the shape of a right triangle with base b = 38 cm and height h = 65 cm and having resistance R = 1.1 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 = 1.1 T pointing in the positive z-direction...
