Introducing the strongest magnets available at first4magnets! N52 grade neodymium was the strongest magnetic material commercially available until it was recently surpassed by the marginally stronger N55 grade, which is available upon request. Even the smallest N52 neodymium magnet in our range, 10mm (0.39") diameter x 2mm (0.08") thick, has an impressive pull strength of 1.6kg (3.53lbs).
Large N52 grade neodymium magnets are so powerful that special care needs to be taken when handling them. Not only are they the some of strongest magnets available, they have an incredible depth of field and can attract each other, or a steel surface through distances of several inches.
