This page is here to provide an explanation for finding the direction of magnetic field. Since magnetic field is a cross product, finding its direction can be confusing at times, and you'll be asked many questions involving the direction of the field due to a moving charge, a current carrying wire, a current carrying coil, a bar magnet, etc. Hopefully this should work as a resource to come to when confused about anything regarding '''direction''' of magnetic fields! | |||

This page is here to provide an explanation for finding the direction of magnetic field. Since magnetic field is a cross product, finding its direction can be confusing at times, and you'll be asked many questions involving the direction of the field due to a moving charge, a current carrying wire, a current carrying coil, a bar magnet, etc. Hopefully this should work as a resource to come to when confused about anything regarding direction of magnetic fields!
The Main Idea
You previously learned about electric fields, and how a charged particle, or group of charged particles create a field in a specific pattern due to those particles' orientations. Magnetic field works in a similar fashion, but remember that it doesn't come from simply a charged particle, but a moving charged particle, with a velocity v. Due to this new concept, we start to see some new patterns that you should want to get very familiar with.
A Mathematical Model
What are the mathematical equations that allow us to model this topic. For example [math]\displaystyle{ {\frac{d\vec{p}}{dt}}_{system} = \vec{F}_{net} }[/math] where p is the momentum of the system and F is the net force from the surroundings.
A Computational Model
