AOMAG Ceramic Magnets 7-303578JFA Editorial Review
The Ferrite Ring Magnet is a great choice for science experiments that require a strong magnet. The magnet has a lifting capacity of between 325-370g and can pick up about 100 paper clips. Its inner hole diameter is 2-1/4". Although the gauss rating is not posted on the box, it is a very powerful magnet that should be handled carefully to avoid cracks. One customer used it to attract micro metallic particles in their car's transmission and reported that it can withstand temperatures up to 200 F+. Overall, customers were satisfied with their purchase and found it to be well made and heavy-duty.
