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 126 turns of wire and is 15.0 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 4.00 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 2.00 s. What is the magnitude of the average induced emf (in V) in the square loop during this time? V

The figure below shows a cross section of an "infinitely" long solenoid (circle) that has n=18000 turns/m; the axis of the solenoid (a bold dot) is perpendicular to the plane of cross section. The radius of the solenoid, r=87 cm. A square frame with a side a=8 cm is located in the plane of cross section. The current in the solenoid is I=3.33 A and it does not change with time, the resistance of the frame is R=13 Ω. The frame is rotating at 6000 turns/min with respect to one of its sides.Find the value of the magnetic field inside the solenoid: B=   T.Find the maximum value of induced e.m.f. in the frame: ℰind=   V.Find the maximum value of induced current in the frame: Iind=  A.

A long solenoid has a length 7.9-m, radius 3.5-cm, and 370 turns. It surrounds coil of radius 6.9 meters and 73 turns. If the current in the solenoid is changing at a rate of 710-A/s, what is the magnitude (absolute value) of the emf induced in the surrounding coil? |emf|= = V (Show at least 2 significant figures.)

You are working at a company that manufactures solenoids for industrial and research use. A client has ordered a solenoid that will be operated by a 1,000 V power supply and must be of length { = 36.0 cm. A cylindrical experimental package of radius r. = 1.85 cm must fit inside the solenoid. The client wants the largest possible magnetic field inside the solenoid. The thinnest copper wires allowed by your company are AWG 36, which corresponds to a wire diameter of d, = 0.127 mm. You determine the maximum magnitude of magnetic field (in T) that can be created in the solenoid to report to the client. (The resistivity of copper is 1.7 x 10-80: m.)
