Get a powerful neodymium block magnet with a pull force of 16 pounds. This magnet measures 3/4" in length, 1/2" in width, and 1/4" in thickness.
Use this neodymium block magnet for holding objects to magnetic surfaces and physics experiments. Magnetized through the thickness, the poles are on the 3/4" x 1/2" surfaces of the block magnet.
It's made of grade N45 neodymium, iron, and boron magnetic alloy blend. It's also nickel-plated for a shiny corrosion-resistant finish that withstands years of use.
Please note: Neodymium magnets are more brittle than other types of magnets and can crack or chip. Do not try to machine (cut) them. To reduce the chance of chipping, avoid slamming them together.
