Question

How should the small cross section of the laminations in the metallic components of electromagnetic motors be oriented relative to the direction of the varying magnetic field B vector?

Group of answer choices

a)Perpendicular to the B vector (parallel to the eddy currents loop)

b)Parallel to the B vector (perpendicular to the eddy currents loop)

Which is correct?

Answer 1

Ans. If the small cross section of the lamination is oriented perpendicular to the B vector in the metallic component of electromagnetic motor then there will a maximum amount of force will act on the piece of lamination

f=qvB..............As =90 then maximum force

f=qvB   

in other case that is parallel to vector B force will be zero as the =0

so the option A is correct
