10. A square frame made of copper wire (ρ = 16 nom • m) cross-sectional area mm2 Spr = 1.5, placed in a magnetic field of B = 0.20 T, so that its plane is perpendicular to the lines of magnetic induction. What is the charge q will be held on the frame with a field failure, if the area of the frame S = 40 cm2?
