Question

(Figure 1) shows a 19-cm-diameter loop in three different magnetic fields. The loop's resistance is 0.50 Ω .

Figure 1 of 1The figure shows three positions of a circular loop in the magnetic field labeled a, b, c. Position a shows a loop on the plane. Magnetic field B flows out of the page and is increasing at 0.50 teslas per second. Position b shows a loop on the plane. Magnetic field B flows into the page and is decreasing at 0.50 teslas per second. Position c shows a loop with the horizontal axis. Magnetic field B flows into the page and is decreasing at 0.50 teslas per second.

Part A

For case (a), what is the induced emf?

Part B

For case (a), what is the induced current?

Part C

For case (a), what is the direction of the current?
