Or a scrap yard crane lift magnet, 100amps @ 240vdc
Max.

About 300 horsepower worth of, "pull"?
You could remove your refrigerator from the kitchen without removing the wall first.

 

ok, i was just curious if i would have to cut throughout he plexiglass bottom and solder the magnet and whatever object i end up using. Reason i asked is because i can get (what I'm assuming to be) a much stronger magnet if i go with a "holding magnet" rather than "pulling magnet". For example, i can get a holding magnet that can sustain 55 lbs vs a pulling magnet that can sustain about 5 lbs.




heres what I'm looking at.

Why would you need 50 pounds of force to move microscopic size particles?
Have you tried a refrigerator magnet yet?

 

i have a couple neodymium magnets, problem is i can't find a way to judge the actual force of the electromagnet before i buy it, so i figured aim high as i can always tone it down where i can amp it up if its not enough to get the results i want.

 

OK. Happy shopping.

 

Hey if I'm way off here just tell me thats why I'm here. This is all just guestimation on my part.

 

ps this is essentially what I'm trying to put together.

 

so a weaker magnet you think?

 

no one?
