Right hand rule for induced current in a loop

WebThe direction of the current induced can be determined by using the right-hand thumb rule. The thumb should be aligned in the direction of the induced magnetic field due to the magnet moving towards or away from the conducting coil and the curled fingers show the direction of induced current. This induced current is also called Eddy current. WebUsing the right-hand rule again, as indicated in the figure, shows that the current must flow in the direction shown in Figure 4(c). Figure 20.36 Lenz’s law tells us that the magnetically induced emf will drive a current that resists the change in the magnetic flux through a …
