Two current-carrying wires are perpendicular to each other. The current in one wire flows vertically upwardand the current in the other wire flows horizontally toward the east. The horizontal wire is 1 m south of the vertical wire. What is the direction of the net magnetic force on the horizontal wire? Explain.

There is no net magnetic force on the horizontal wire.

Explanation:

The magnetic field due to vertical wire is in same plane in which the horizontal wire is present.

Magnetic force on the wire is given by the formula:

F = I L B sin θ

Where, I is the current through the wire, L is the length, B is the magnetic field strength and θ is the angle between the direction of current and magnetic field.

As θ = 0, therefore F = 0
