Magnet glue.

[john8750]

OK  I have magnets and metal plates. I need to glue them down. Like JB weld or what would be better?
Going to make a sail actuated yoke with 3X2 inch metal plates bolted inside the yoke, then glue 2X1X1/4 mags to the inside of the plates. I will start with 200 turns around a 1 1/2 inch coil form of #22 wire.
I have a good supply of choppy one directional wind. And realize the electrical current produced will be mostly unusable. I'm just enjoying working on collecting free energy.
 

Thanks

JB weld works okay, magnets will stay put on their own pretty good

Do it for fun - that's the best reason of all.

JB Weld is OK.  It's how you apply it that's most important.  Wipe off any oil/dirt/rust as carefully as you can first.  A bit of sanding (to the metal plate) wouldn't hurt either.  Try to have enough glue to squeeze out around the sides without going overboard.  A fillet or a bead of glue all around the edge will keep water from getting between magnet and plate, which would both corrode and freeze/thaw split the joint (if you live where it gets cold enough, of course).
