Created by StemPy LabThe two conductors of a flat lamp cord run side by side, mm apart, and carry the same current of A in opposite directions, out and back. What is the size of the force on each metre of one conductor?

← A doughnut-shaped winding of 700 turns is carrying 2.5 A. A probe inside the ring sits on a circle of radius 14 cm about the centre of the ring, which runs round the ring. What field does the probe read?A long straight wire carries 54 A. A circular coil of one turn and radius 7 cm lies in the same plane as the wire, with its centre 30 cm from the wire. What current in the coil makes the field at the centre of the coil zero? →
