A long solenoid with N₁ windings and radius b surrounds a coaxial, narrower solenoid with N₂ windings and radius a < b as shown in (Eigure 1). The length of solenoids is A. At the far end, the outer solenoid is attached to the inner solenoid by a wire, so that current flows down the outer coil and then back through the inner coil as shown. Figure Leads N₁ Solenoids connected at this end 1 of 1
▼ Part A The two leads are attached to a supply circuit that includes a battery, supplying current I as indicated.
