About This Product
Flat ceramic magnets are used in pairs to make a uniform field for motor-effect and Faraday's law experiments, and for showing attraction and repulsion between faces. Because the poles are on the large faces, two magnets can be fixed to a yoke with a narrow gap between them.
Frequently Asked Questions
Which faces of the Magnadur magnet are the poles?
The magnets are magnetised across the large faces, through the thickness, so the poles are on the two broad faces.
