Neodymium Rare Earth Magnet 1" X 1/2" Disc Nickel Coated Grade N52 Ultra Powerful Industrial Grade

Neodymium Rare Earth Magnet.  1" x 1/2" Disc Grade N52 Nickel Coated  Exceptionally powerful. These are very serious industrial grade magnets and must be handled appropriately with extreme care.  1" in diameter, 1/2" thick.  So powerful it would be very difficult to separate two that have joined together.
