Force due to a Magnetic Field is equal to..
(Absolute Value of the charge) *
(perpendicular velocity of particle) *
(magnetic field)
In a uniform magnetic field, a particle who's initial veloticy is perpendicular to the field moves in what way?
a circle.
The radius of the circle a particle moves within a uniform magnetic field is found with..
r = (mv)/(qB)

radius is (mass*velocity)/(charge*MagneticField)
When a particle is shot into an electric field with a perpendicular magnetic field, the speed of the particle is found with...
v = E/B
velocity = EnergyOfElectricField/MagneticField
Magnetic Force on a current carrying wire?
F = I*l*B
Force is Current * length of wire* magnetic Field
What are the relationships between a magnetic field, current and radius (in current carrying wires)
B is directly proportional to I and inversely proportional to r.

B » I/r
What is the right hand rule?
Point your fingers towards the velocity of a particle, then point your palm in the direction of the magnetic field. Your thumb will point in the direction on the force.
What is the magnetic field between two wires?
