An electromagnet if formed by pushing current through a coil. If the circuit is truly open, current will cease to flow, thus no electromagnet.

Is a circuit breaker an electromagnet?
No.
A safety device that uses an electromagnet to shut off the circuit is called a?
A safety device that uses an electromagnet to shut off the circuit is called a contactor.
How does closed circuit work?
A closed circuit works by having electricity flow in a complete circuit or circle or any closed shape.
What happens when a curcuit is closed?
To close a circuit in electrical terminology is to close any open devices that are in series with a connected load. Once this happens the current will flow through the load and the load is then termed as energised. In the case of a motor circuit the motor will operate. In the case of a lighting circuit the lamps in the circuit will energise and light the area in which they are installed.
Do you need an open circuit or closed circuit for a garage door open light?
In order to illuminate the light, you need a closed circuit. It would be normally open, and closed to indicate that the door is open.
What happens when a circuit is closed?
when a circuit is closed, electricity can move though it.
What happens to an electric current when a circuit is closed?
If the circuit is closed the electric current will be closed as well.
What happens when a circuit closes?
when a circuit is closed, electricity can move though it.
What happens when the circuit is closed?
Current flows
How is electricity transformed into motion?
A motor transforms electricity. Inside the motor, there is a permanent magnet and an electromagnet, which can rotate. When the circuit is closed, the electromagnet is constantly repelled and attracted to the permanent magnet. This will cause the electromagnet to turn. It also causes anything that is attached to the electromagnet to turn, causing motion.
Is a circuit breaker an electromagnet?
No.
How does a circuit breaker use an electromagnet?
The electromagnet in the circuit breaker is used for instantaneous tripping if short-circuit condition arises. At defined current level the electromagnet develops the force high enough to cause the tripping of the mechanism.
How is a circuit diagram related to a closed circuit?
A circuit diagram could be related to a closed circuit if the diagram is of a closed circuit.
When a circuit is not closed?
When a circuit is not closed it is not operating.
When is a circuit is closed?
When a circuit is not closed it is not operating.
A safety device that uses an electromagnet to shut off the circuit is called a?
A safety device that uses an electromagnet to shut off the circuit is called a contactor.
What is another word for closed circuit?
Another word for closed circuit is a loop.
