Question

The figure shows a stationary conductor, whose shape is similar to the letter "e" (a = 58.4 cm), that is placed in a constant magnetic field of magnitude B = 0.515 T directed out of the page. A 58.4 cm long, straight conducting rod pivoted about point O rotates with a constant angular speed of 2.14 rad/s. Determine the induced EMF in loop POQ. Tries 0/12 If the conducting material has a resistance per unit length of 5.66 ?/m, what is the magnitude of the induced current in loop POQ at t = 0.290 s?

Explanation / Answer

The magnetic field varies with the distance from the wire, so the magnetic field through the loop isn't a constant. That means you can't simply take some value for B and multiply it by the total area of the loop to find the total flux. You're going to have to integrate.
