Problem 3.360

A large plate of non-ferromagnetic material moves with a constant velocity v=90 cm/sv=90 \mathrm{~cm} / \mathrm{s} in a uniform magnetic field with induction B=50mTB=50 \mathrm{mT} as shown in Fig. 3.98.3.98 . Find the surface density of electric charges appearing on the plate as a result of its motion.

Reveal Answer
σ=ε0vB=0.40pC/m2\sigma=\varepsilon_{0} v B=0.40 \mathrm{pC} / \mathrm{m}^{2}
