Is an electric current possible without a source, explain with examples.

Yes, it is possible. As you know, the directional movement of infected particles is called electric current. This movement is created using the electric field of the current source. But a short-term electric current can be created without a source. You need to take a metal rod and throw it vertically from a certain height. When hitting the ground, the rod stops, and the electrons continue to move by inertia. At this moment, an electric current is created. It is called inertial.
