Force due to a Magnetic Field is equal to..
|
|q|vBsin(θ)
(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.
