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 and a magnetic field is produced. While this magnetic field is being produced, there is a force acting upon the wire causing it to twist. An example of this phenomenon is the movement of a compass needle by the Earth's magnetic field or hanging a coil near a bar magnet will cause it to twist in the direction of the magnetic field.
A Mathematical Model
Torque is created from the magnetic forces acting upon a coil.
This is the overall equation for determining magnetic torque.
is the dipole moment of the magnet
is the magnetic field created by the magnet (in units of Tesla)
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. As a Biology major, field work is a large part of what I do, especially studying ecological systems and different habitats. In order to navigate in unfamiliar locations, such as deserts and dense tropical forests, scientists rely heavily on basic survival skills and this includes the use of compasses and maps. Physics, biology, and chemistry make up part of the science family and each heavily depends on the other, this is why it is important to study each one to bridge the relationship.
