1
Q
Magnetic force of a particle moving thru a B field
A
F=qvBsintheta between velocity and B
2
Q
MAgnetic force of a current carrying wire
A
F=ILBsintheta, where theta is the angle between B and direction of current
3
Q
torque on a current loop
A
T=muBsintheta, where mu=IAN, and N is number of coils in the current loop
ALSO
T=BIAN sin theta
4
Q
motional emf
A
E=Blv
5
Q
static emf
A
E=-ndeltaphi/delta t
6
Q
parallel conductors carrying current in the same direction, attract or repel?
A
attract
7
Q
Magnetic force of a current carrying wire
A
F=ILBsintheta, where theta is the angle between B and direction of current
