Magnetic Torque

Summary

Magnetic torque is a phenomenon that occurs when the magnetic field produced causes a current-carrying wire to twist out of proportion.

The Main Idea

The idea behind this concept is that as the current flows through the wire, a magnetic field is produced. While this magnetic field is being produced, there is a dipole moment which in combination with the magnetic field causes the wire to twist. An example of this phenomenon is the movement of a compass needle by the Earth's magnetic field or if you hang a coil near a bar magnet it will twist in the direction of the magnetic field.

A Mathematical Model

This is the overall equation for determining magnetic torque.

Examples

Torque on Current Carrying Loop

Simple

If there is a current-carrying wire with a magnetic field of 0.5 T and a dipole moment of 0.23, what is the torque produced on the wire?

Connectedness

Utilizing a compass is a basic survival need and it just so happens to depend on the torque produced by the Earth's magnetic field.
