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 table top.
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 + bt, where a and b are constants. Determine the
emf that is induced in the loop if b = 10.0 A/s, h = 1 cm , w = 10.0 cm, and L = 100 cm. What is the direction of the induced current in the rectangle?
