My Bendini magnet in the wrong way - help please

[zac123]

hi all,

i'm bought myself a little 3 pole bendini magnet motor just as a little garage project to help me learn the basics but unfortunately i put one of my magnets in round the wrong way using super glue.

can anyone advise me the best way to get it out?

i tried acetone but i think the hole is too tight for the acetone to get down there.

many thanks

Heat up the aliminium with a butane torch so the hole expands. Probably the glue will go away too. Then you kan shake out the magnet or use another magnet to pull it out.

a ha, butane torch , yes i didnt think of that. thanks. i already thought of the magnet trick. i have rare earth magnets that should do the trick but i'll have to go a buy a butane torch from the local WICKES.

many thanks.

One notice: heating will unavoidable heat the magnet too and normal Neo magnets normally allowed to heat up 80°C, beyond that they gradually loose their strength.  Of course this is a smaller price than making another hub...

You're welcome
Put a heatsink (another neodymium) on the magnet so it wont heat up as much so the magnet doesn't expand too.
