I was thinking about electromagnets today and a thought popped up in my mind on what would be a very simple way to create an electromagnet.
Although I have not built and tested it, I am pretty sure that it will function as an electromagnet even though it will be a lot weaker in magnetic strength than standard electromagnets.
Below is a drawing I made of this very simple electromagnet. The working principle is that an iron washer is cut in half and then one half of that iron washer is superglued to an insulated, current carrying straight conductor/wire. The half iron washer will function as an electromagnet when electrical current is applied to the wire.
Would this be one of the simplest ways to create an electromagnet?
EDIT
I would like to point out that this iron-based electromagnet would not be the simplest electromagnet to create, yet it would be one of the simplest electromagnets to create.
