What does "electromagnet de-energized" imply about a switch?

When an electromagnet is de-energized, it means that the electrical current supplying power to the electromagnet has been cut off. In this state, the electromagnetic force that normally keeps the switch closed is no longer present. As a result, the mechanism that secures the switch is released, causing the switch to open. This is a fundamental principle of how electromagnetic switches operate.

In the context of various types of electrical control systems, an open position signifies that the circuit is broken and current cannot flow, which aligns with the de-energized state of the electromagnet. Other options, such as a switch being in a closed position, malfunctioning, or automatically resetting, do not accurately reflect the outcome of the electromagnet being turned off. Therefore, the correct understanding is that when the electromagnet is de-energized, the switch opens, thereby preventing the flow of electricity through that circuit.
