WebOne experiment Faraday did to demonstrate magnetic induction was to move a bar magnet through a wire coil and measure the resulting electric current through the wire. A schematic of this experiment is shown in Figure 20.33. He found that current is induced only when the magnet moves with respect to the coil. WebI do not think electric current flows through bar magnets. (1)If, however, we are talking about magnetic fields, outside the magnet, they flow from north to south. (2) Magnetic field lines are closed curves (3) Therefore, it makes sense that they flow from south to …
