... ⇒ dΦ/dt = 0 ⇒ there is no emf induced and no current. When the loop is moving to the right: the magnetic field at the position of the loop is increasing in magnitude. ⇒ |dΦ/dt| > 0 ⇒ there is an emf induced and a current flows through the ring. Use Lenz’ Law to determine the direction: The induced e ...

... PhET: Magnet and Compass. Determine the N and S poles of a magnetic dipole. Observation: A compass needle points in the direction of the net magnetic field (due to other sources) at the location of the compass needle. Explanation: If the compass needle points in a different direction than the magnet ...
