In Fig. 32-4(a) there is a uniform magnetic field in the +xdirection, with a value of B

Question:

In Fig. 32-4(a) there is a uniform magnetic field in the +xdirection, with a value of B = 0.20 T. The circular loop of wire is in the yz-plane. The loop has an area of 5.0 cm² and rotates about line CD as axis. Point-A rotates toward positive x-values from the position shown. If the loop rotates through 50° from its indicated position, as shown in Fig. 32-4(b), in a time of 0.20 s,

(a) What is the change in flux through the coil,

(b) What is the average induced emf in it, and

(c) Does the induced current flow directly from A to C or C to A in the upper part of the coil? (a) D Fig. 32-4 (b) 50 100 B co *
