Terminal Velocity of a Conducting Loop

Question

A rectangular conducting loop with mass $m$, width $w$, and resistance $R$ falls under the influence of gravity through a region containing a uniform horizontal magnetic field $B$. What is the magnitude of the loop's terminal velocity, $v_t$?

Accepted Answer

$$v_t = \dfrac{mgR}{B^2w^2}$$

Answer

$$v_t = \dfrac{mg}{B^2w^2R}$$

Answer

$$v_t = \dfrac{mgR}{Bw}$$

Answer

$$v_t = \sqrt{\dfrac{mgR}{Bw}}$$
