1
Q
Magnetic force of a charge carrying wire WITHIN a magnetic field
A
Fm= I x L x B x Sin (0)
2
Q
Field strength around a wire
A
B= μ x I / 2πr
3
Q
RHR
A
thumb –> direction/motion
Pointer –> field
Rest –> current
4
Q
Induced emf (voltage) formula
A
emf = πr^2(change in B/ change in t)
4
Q
voltage (emf) in wire based on velocity
A
E=B x L x V
