Making Permanent Magnets
Making Permanent Magnets
(OP)
Hi All,
What a wonderful site this is! Thanks for being a great community.
I would like to make a permanent magnet at the end of a piece of 4130 hollow bar about 1/2" OD.
Is it possible to make a reasonable permanent magnet on the end of this tube?
I have no idea of how this would be properly done but my thought was making a hollow electromagnet that fits over my 1/2" and pulsing it on and off repeatedly? Just a thought.
I was not sure where best to post this questions. Please advise if it should be elsewhere.
Kind Regards, Iain.

RE: Making Permanent Magnets
I'm thinking also, that if the magnetic field is aligned with the bar, the whole bar will be a magnet, rather than having a magnet at the end. And if the field is at right angles to the bar, it'll be short-circuited, so to speak, through the extension of the bar, so you'd have a fairly weak magnet.

I'm not saying this is the most efficient way to make a magnet, but I always wanted to try this myself... this just reminded me again.

Depends on what you need the magnetism to do.
Traditionally a permanent magnet like Neodynium is adhered to end of non-magnetic bar.

Are permanent magnets (the rare earth metal ones) created or discovered?
