PHYS 1502Q Chapter Notes - Chapter 13: Net Force, Electrical Energy, Potential Energy
Document Summary
Forces and torques exerted on current carrying wires and magnetic fields. Forces on straight and curved wires in constant magnetic fields. Torque on a closed loop of current in a constant magnetic field. Dipole moment associated with a current loop. Potential energy that is associated with a current loop in a magnetic field. = q vi b avg b avg b. A = v of charge carriers per volume olume of the wire in the b field. L = vector whose direction is that of the average velocity (component of l perpendicular to the b field) Force of the moving charges charges are constrained force on the wire. F = i b is valid for all wires in a magnetic field. The force on a wire in a magnetic field does not depend on the shape of the wire. Depends on the distance perpendicular to the field between the endpoints of the wire.
