Rare Earth (NdFeB) Magnets for Science and Engineering

Rare Earth Magnets

Rare earth magnets are the strongest magnets by weight and have multiple uses in science, engineering, industry, magic and more. All our magnets have a maximum operating temp. of 80C & a Curie temp. of 310C; tolerance +/-0.05mm.

Although these magnets are not marked north/south you can determine this with an inexpensive compass. and point it at the top or bottom of the magnet.

For more variety, click on the links below. Note that there are 25.4mm per inch or you can assume that 2.5mm is roughly 1/10th of an inch.

~25mm (2.5cm) = ~1 inch; 2.5mm (0.25cm) = ~ 1/10 inch; 3E=x 1000.
