Will Rare Earth Magnets stick to stainless steel?
So even though a Magnetic Separator will not capture all stainless steel, those with a high magnetic attractive force (eg Rare Earth Magnets) will attract and capture a high percentage. This is ideal when trying to reduce the amount of metal passing through final stage Metal Detection.
How long do rare earth magnets last?
How long will a neodymium magnet last? Neodymium magnets are permanent magnets, and lose a fraction of their performance every 100 years if maintained within their optimum working conditions.
Will Rare Earth Magnets pick up coins?
To collect coins, you will need a rare-earth magnet. … If the coins are magnetic, they are attracted to the magnet. Due to its strength, the rare-earth magnet can pick up a chain of coins, with each coin attached to the other in a chain formation.

Will a magnet pick up a dime?
Even though it contains Nickel (Ni), a ferromagnetic material, they aren’t visibly attracted to magnets. In fact, they don’t interact with magnets like many other non-magnetic materials. What is interesting is that dimes and quarters will visibly interact with a moving magnet.
How do I dispose of magnets?
If you do not have any other options, throw them in the trash bin. After all, you cannot recycle fridge magnets. Just throw them in the general waste bin if no options arise.
