# Answer on Electromagnetism Question for Hameed

Question #62184

A horizontal, straight wire carrying 12.0 A current from west to east is in the earthâ€™s

magnetic field B. At this place, B is parallel to the surface of the earth, points to the

north and its magnitude is 0.04 mT. Determine the magnetic force on 1 m length of

the wire. If mass of this length of wire is 50 g, calculate the value of current in the

wire so that its weight is balanced by the magnetic force.
