Magnet surface: Neodymium magnets that are not protected with a surface coating (such as plating) may rust in humid conditions.
Relative cost: Neodymium magnets are more costly than the ceramic types, but pack a much stronger punch. You need a smaller magnet size to achieve the same objective – potentially leading to a lower overall cost as the size of the entire device can shrink.
Care tips: Take care when handling these magnets – especially larger magnets. They are very strong and can snap together or to a steel surface with a strong force! Be careful not to pinch your fingers between these magnets. Note that persons with pacemakers should not allow their devices to be exposed to magnetic fields greater than 5 gauss.
