The figure below shows an end view of a solenoid along its axis. The solenoid has a circular cross section with a radius of r = 3.00 cm. It consists of 110 turns of wire and is 25.0 cm long. Inside the solenoid, near its center and coaxial with it, is a single loop of wire in the shape of a square, with each side of length ℓ = 1.00 cm. (The plane of the square loop is perpendicular to the solenoid axis.) A square with sides of length ℓ is completely inside of and concentric with a circle of radius r.

(a) Initially, there is a steady current of 2.00 A through the solenoid. What is the magnitude of the magnetic flux (in T · m2) through the square loop? T · m2

(b) The current in the solenoid is then reduced from its initial value to zero within 2.50 s. What is the magnitude of the average induced emf (in V) in the square loop during this time?
