Magnetic Field

• Any region of space where a moving charge feels a force
• Moving charges generate a magnetic field around themselves (see right hand screw rule)
• Unit for magnetic field is the Tesla (T)

Right Hand Screw Rule

Right Hand Slap Rule

Lorentz Force

F = Bqv force on a charge moving perpendicular through an electric filed

F = BIL force on a current carrying wire perpendicular to an electric filed
