A square loop of side length a is rotating with angular fre-quency w in a constant, uniform magnetic flux density a_z B_0. The loop rotates right hand rule-wise around the y axis. Make a plot of the emf in the loop vs. time, assuming that the loop is in the xy plane at t= 0.Include axis labels with values.

Problem 7: Part (a)  Express the current induced in the loop, I, in terms of ε and R.  I = ______ Part (b)  Calculate the value of I, in amperes. I = ______

Answer c

In the figure below, a semicircular conductor of radius R = 0.220 m is rotated about the axis AC at a constant rate of 170 rev/min. A uniform magnetic field of magnitude 1.32 T fills the entire region below the axis and is directed out of the page. R Воли (a) Calculate the maximum value of the emf induced between the ends of the conductor. (b) What is the value of the average induced emf for each complete rotation? (c) How would your answers to parts (a) and (b) change if the magnetic field were allowed to extend a distance R above the axis of rotation? (Select all that apply.) O The value in part (a) would increase. The value in part (a) would remain the same. The value in part (a) would decrease. The value in part (b) would increase. The value in part (b) would remain the same. The value in part (b) would decrease. (d) Sketch the emf versus time when the field is as drawn in the figure.
