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.
Represents torque and its units are
is the dipole moment of the magnet
is the magnetic field created by the magnet.
A Computational Model
How do we visualize or predict using this topic. Consider embedding some vpython code here Teach hands-on with GlowScript
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?
Middling
Difficult
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.
