Multiple Choice

A current-carrying 2.0-cm long segment of wire is inside a long solenoid (radius = 4.0 cm,n = 800 turns/m,current = 50 mA) .The wire segment is oriented perpendicularly to the axis of the solenoid.If the current in the wire segment is 12 A,what is the magnitude of the magnetic force on this segment?

A) 22 $\mu$ N
B) 16 $\mu$ N
C) 18 $\mu$ N
D) 12 $\mu$ N
E) 0 $\mu$ N
