When considering an induction coil in an electromagnet, what is true about the current flow when electromagnetic force is not doing work?

When an induction coil in an electromagnet is in a state where electromagnetic force is not performing any work, it typically indicates that the magnetic field generated is stable and does not require energy input for maintaining its integrity. In this scenario, the electromagnetic system is not actively using power to produce movement or perform any function that would typically require energy.

This means that the primary circuit may have very little current flowing through it. The minimal current flow can be attributed to the fact that the system is in a balanced state. In this state, energy consumption is reduced as the magnetic field does not change rapidly, leading to lower demands on the power source. This situation often arises when the magnetic field is established, and there are no dynamic forces or loads acting on the electromagnet.

In contrast, a very high current flow would indicate that the coil is working hard, overcoming resistive losses and actively doing work to maintain or change the magnetic field. No current flowing would imply a complete shutdown of the circuit, which does not align with the concept of an induction coil that is charged but not doing work. Conversely, current flowing in reverse would suggest a different operational condition altogether, typically associated with changing magnetic fields or other active processes.

Thus, very little current flowing in this
