An insulator such as rubber or plastic can stop the flow of electrical current by preventing the movement of electrons. Additionally, a switch can be used to interrupt the circuit and halt the flow of electricity.

When the electrical current stops in an electromagnet, the magnetic field produced by the coil will dissipate, causing the magnetism to disappear. The electromagnet will no longer attract or repel other magnetic materials until current is passed through the coil again.
Materials that are considered insulators, such as rubber, plastic, and glass, can stop or greatly reduce the flow of electrical current. These materials have high resistance to the flow of electricity, preventing electrons from moving freely through them.
A flow of electrical charges running through a medium is known as an electrical current.
True. Moving current, such as in an electrical circuit, carries electrical energy in the form of kinetic energy of the moving charges.
Yes, the current in an electrical circuit can be negative if it flows in the opposite direction of conventional current flow.
