A conducting loop is pushed at a constant velocity

v

into a magnetic field. An external force

F_{ext}

is required to maintain this constant velocity against the magnetic braking force

F_{mag}

. What is the relationship between the rate at which the external force does work (

P_{ext}

) and the rate of thermal energy dissipation in the loop (

P_{dissipated}
