Electrician Family, Dad Teaches Sons about Coils and Contactors, and how they operate, Thoughts?

What happens here

The dad further explains that the magnetic field generated by an energized coil has a practical application: it can pull against a piece of steel. This interaction is the fundamental mechanism behind a contactor, an electrical switching device. A visual aid reinforces this concept by illustrating a solenoid (a type of coil) interacting with a steel core.

Goal: Explain how a coil's magnetic field creates a contactor.

Tools and materials

  • Solenoid — Visual aid to demonstrate how a coil's magnetic field pulls a piece of steel

What they say

Hide

>> Coil is a just a loop of wire, right? >> When you energize a loop of wire, what happens? >> It creates a magnetic field and then that magnetic field will pull against a piece of steel and create a contactor. >> Okay. >> Okay. >> You can take wires around your finger and wrap it and wrap it and wrap it and that's a coil. But obviously there's some engineering to make sure they're sized properly. But that's really all it is. This is actually a lighting contactor. This will control 12 circuits
