A loop of wire in the shape of a rectangle of width w and length L and a long, straight wire carrying a current I lie on a tabletop as shown in the figure below.
(a) Determine the magnetic flux through the loop due to the current I
. (Use any variable stated above along with the following as necessary: μ0
(b) Suppose the current is changing with time according to I
, where a
are constants. Determine the magnitude of the emf that is induced in the loop if b
= 1.00 cm, w
cm, and L
(c) What is the direction of the induced current in the rectangle?
