Help with making an electromagnet Answered

It’s not as simple as it sounds I need to make it pick up things ( screws maybe screwdriver)and I need to be able to hide it somehow under my sleeve so I can trick people in to thinking I have magical powers.


It's true that you can get some powerful permanent magnets, but if you want to turn one on and off, you need an electromagnet. There are instructions at https://www.instructables.com/id/Create-an-electric-magnet/<br />Wrap lots of fine enameled wire, maybe 100 feet or 30 m around a nail. Use a good battery and switch. Electromagnets drain batteries pretty fast.<br /><br />The trouble is, they only work over an inch or a couple of cm unless they are much larger than you can hide up your sleeve.<br /><br />

Electromagnets can also heat up pretty fast, if you've got one which is carrying a lot of current.

Depending on the effect you want, the magnet may not need to be switchable. As  I say, you may want to do a bit of research on what the pros are using.

Just get a magnet. Have a good poke around 2nd hand shops (cheap-junk vendors) - look for those old 80's "magnetic sculptures", I got one dirt-cheap last week.


These days you can get permanant magnets FAR more powerful for their weight than any reasonable electromagnet will be. Get to a good magic supply store and they'll have some very interesting effects based on these.

Oh aye, you can order variety-packs off the internet. (URL not needed, easy enough to find)
