Moving the magnet around the inductor will change the magnetic field inside the inductor, which will cause current to flow through the inductor. This phenomenon is called electromagnetic induction. The current flowing in the inductor is called the induced current. The induced current flows when the magnet moves and the magnetic field changes. When the magnet stops, the magnetic field does not flow. The intensity of the induced current is proportional to the amount of change in the magnetic field.
What is the direction of the induced current?
The inductor attempts to create a magnetic field that interferes with the external magnetic field. Therefore, the direction of the external magnetic field and the induced current is opposite.
