Parallel wires exert magnetic forces on each other. What about perpendicular wires? Imagine two wires oriented perpendicular to each other and almost touching. Each wire carries a current. Is there a force between the wires? Explain what happens in this situation.

Answer #1

Suppose one wire is along the Y axis and the other is along the X axis

The magnetic field acting on the wire segment on the negative x axis is in opposite direction to the magnetic field acting on the wire segment on the positive x axis.

Hence the force on the wire that is on the negative x axis due to the perpendicular wire will cancel out the force on the segment on the wire that is on the positive x axis.

Hence the net force between 2 perpendicular wires will be zero.

If two wires carry current next to each other, they will exert a force on each other. The force is caused by magnetic fields. One current creates a magnetic field, and this field exerts a force on the other current. The magnitude of the field created by a long, straight current-carrying wire is given by Equation 1 below; B= (μ0i)/(2πr) where i is the current and r is the distance from the wire. The magnitude of the force exerted on...
