Question

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. Determine the magnetic flux through the loop due to the current I. (Use any variable stated above along with the following as necessary: mu 0 and pi.) Suppose the current is changing with time according to I = a + bt, where a and b are constants. Determine the magnitude of the emf that is induced in the loop if b = 18.0 A/s, h = 1.00 cm, w = 13.0 cm, and L = 1.35 m. What is the direction of the induced current in the rectangle? clockwise counterclockwise The magnitude is zero.
