Magnetic flux – any area that has a mag. Field passing through it

90° angle = Max flux

Parallel = Min flux

Magnetic Flux:

Gauss’ Law for

Magnetic Force on a Moving Charge:

*Conditions for this force!

1) must

have field present

2) charge

3)q m/b

pos. or neg.

4) q experiences max. force when moving PERPENDICULAR to

field
