Q13: A loop of wire in the shape of a rectangle of width w and length L and a long, straight wire carrying a cur- rent I lie on a tabletop as shown in Figure P31.13.
(a) Determine the magnetic flux through the loop due to the current I.
(b) Suppose the current is changing with time according to I = a 1 bt, where a and b are constants. Determine the emf that is induced in the loop if b = 10.0 A/s, h = 1.00 cm, w = 10.0 cm, and L = 1.00 m.
(c) What is the direction of the induced current in the rectangle?
