Question

A solenoid has a 3cm x 3cm square cross section, 1800 turns, alength of a 75cm and carries a 12A current. What is the maximum torque on this solenoid if it sites in auniform magnetic field of 5 mT? I found the magnetic field inside this solenoid to be .0362mT. Will rate LIFESAVER! A solenoid has a 3cm x 3cm square cross section, 1800 turns, alength of a 75cm and carries a 12A current.

Explanation / Answer

mag moment of solenoid = N I A   = 1800* 12 * 0.03*0.03 =   19.44 . And max torque on any coil is   magnetic moment *external mag field so... .    maxtorque = 19.44 * 0.005 =   0.0972 N-m . (you actually dont need the B field created by the solenoidfor this one...) .
