(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 magnitude of the emf that is induced in the loop if b = 14.0 A/s, h = 1.00 cm, w = 20.0 cm, and L = 1.10 m. 

(c) What is the direction of the induced current in the rectangle? clockwise counterclockwise The magnitude is zero.
