Tips:
Strong neodymium block magnets are brittle; they can be broken or can splinter in a collision.
One should wear gloves and protective glasses when handling these big size square magnets, because splinters could disengage and fly from the magnets.
You should avoid having constant contact with magnets of any size and keep a distance of at least 3 feet to large magnets
