Question

An aluminum ring of radius r₁ and resistance R is placed around one end of a long air-core solenoid with n turns per meter and smaller radius r₂ as shown in the figure. Assume that the axial component of the field produced by the solenoid over the area of the end of the solenoid is one-half as strong as at the center of the solenoid. Also assume that the solenoid produces negligible field outside its cross-sectional area. The current in the solenoid is increasing at a rate of

?I/?t.

(a) What is the induced current in the ring? (Use any variable or symbol stated above along with the following as necessary: ?₀ and ?.)
I_ring = ?I/?t
