Hey everyone,
I'm struggling with this true/false question. If anyone couldexplain it, I'd greatly appreciate it. Thanks. -A

Suppose that a current-carrying wire placed in a magnetic fieldwill gain kinetic energy as the wire accelerates in response to themagnetic force. If you consider the definition of work (W=Fdcosx),one realizes that the magnetic field cannot do work on a chargedparticle because the force on the particle is perpendicular to itsmotion. Thus, the magnetic force is an exception to therule.

Explanation / Answer

   Although the charged particles are movingperpendicular to direction of field, the wire moves in direction offield therefore work is done on the wire.
