Short Description of Topic
The Main Idea
A Mathematical Model
What are the mathematical equations that allow us to model this topic. For example [math]\displaystyle{ \vec{F}_{magnetic}= \vec{F}_{electricperpendicular} }[/math] where F_magnetic is the force on the mobile charge by the magnetic field and F_electricperpendicular is the force the mobile charge experiences that is caused by the polarization of the metal.
A Computational Model
How do we visualize or predict using this topic. Consider embedding some vpython code here Teach hands-on with GlowScript

History
The Hall Effect was discovered in 1879 by Edwin Herbert Hall while he was attending Johns Hopkins University for his Doctoral Degree. He exposed a gold leaf (metal slab) to a magnetic field perpendicular to its surface and had current flow through the slab. He observed a potential (delta V) perpendicular to the current and also the magnetic field. This means that potential is observed not only in the direction of current flow like usual. This is what led to Hall's discovery o the Hall Effect.
