Lecture 27: Magnetic Force, Torque, Circular Motor and the Hall Effect
Magnetic force on parallel current segments
(attractive forces)
Current loop in a constant B field
Torque about midline 00:
(view from the baseline loop)
General Case:
Circular Motion – Force due to B on qv
Circular Motion – Force due to B on qv
At P1:
At P2:
Hall Effect: Determine the sign of charge carriers
If carriers have + charges:
If carriers have – charges:
Determination of v:
