일반물리학 2 — Magnetic Fields: Problem 22

22 A metal strip 6.50 cm long, 0.850 cm wide, and 0.760 mm thick moves with constant velocity \(\vec{v}\) through a uniform magnetic field \(B = 1.20 \text{ mT}\) directed perpendicular to the strip, as shown in Fig. 28-31. A potential difference of \(3.30 \text{ \mu V}\) is measured between points \(x\) and \(y\) across the strip. Calculate the speed \(v\).
