← A square coil of side 13 cm faces a uniform field of 0.43 T head on, so that its normal is along the field. What is the flux through the coil?A magnet hangs with its north pole just above a flat ring. It is pulled straight up and away. In which sense does the current in the ring flow, as seen from above? →
