Very strong and solid 1/2" diameter discs. They are a great mid-sized general purpose magnet. Good size for science experiments or serious fridge magnets.

This size is also available in grade N52 as part number D82-N52, grade N52 with a Black Nickel finish as part number D82B-N52, in grade N42 with a Black Epoxy coating as part number D82E, diametrically magnetized in grade N42 as part number D82DIA , and in High Temp grade N42SH as part number D82SH.

Need to increase the force? If your application allows it, placing the D82 in a NSC82 steel cup will result in a pull force nearly 4x the pull force case 1 strength!
