A coil lies flat on a horizontal tabletop in a region where the magnetic field points straight down. the magnetic field disappears suddenly. when viewed from above, what is the direction of the induced current in this coil as the field disappears?

Respuesta :

When viewed from above, the direction of the induced current in this coil as the field disappears would be clockwise. To know the direction of the induced current, we use the Lenz's law. It states that the direction of a current induced by a circuit that is due to the change in the magnetic field would be opposing the change in the flux. For this situation, the change in the flux is directed counterclockwise so that the direction of the current induced is clockwise.
