• 28-8 Magnetic Force on a Current-Carrying Wire

• A straight wire carrying a current i in a uniform magnetic field experiences a sideways force

• The force acting on a current element in a magnetic field is

• A flexible wire passes between the pole faces of a magnet (only the farther pole face is shown). (a) Without current in the wire, the wire is straight. (b) With upward current, the wire is deflected rightward. (c) With downward current, the deflection is leftward.

• The direction of the length vector L or dL is that of the current i
