Electromagnets!
in Experiments
Posted
I have a feeling that this has been considered previously, but I'm not sure where... Anyway, I'm looking for some pointers on increasing the strength of a basic home-made electromagnet. I know greater cross-sectional area, more coils of the circut, and greater current will work, but any other suggestions or elaboration on the first three would be appreciated.
Goal of the project: create an electromagnet that will be able to hold securely to a sheet of steel despite sharp pulls of ~150N.
Maximum current available: whatever 1 car battery can offer. Also, sorry for the vague "question," but my plans for this are currently this vague...
