Problem
A straight conductor of length 0.30 m carrying 2.5 A is placed perpendicular to the axis inside a long solenoid. The solenoid has 1500 turns uniformly distributed over a length of 0.50 m. If the conductor experiences a force of 7.5×10−3N, determine the current flowing through the solenoid windings.
(a) 1.3A
(b) 2.7A
(c) 5.3A
(d) 0.27A
