NdFeB Ring Magnets

A thin flat circular magnet where the thickness does not exceed the diameter and there is a hole through the center. Ring magnets are commonly used when a mechanical attachment method is needed to secure the magnet. We carry both straight sided and countersunk magnets. We can also manufacture magnets to our customers’ specifications.

Packaging

Delivery

Shipment Methods
Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.

1: If the weight is under 40 Kgs, we recommend to ship products in shielding boxes by Express.

2: When the weight is between 40Kgs-100Kgs, it can be sent by Express or Air.

3: When the weight is over 100Kgs, it is better to ship them by Ocean.

 

Possible application areas:

Two ring magnets demonstrate “magnetic levitation” – floating caused by magnetism – in an easy and impressive way. You need two axially magnetised neodymium ring magnets and a pen on which both magnets are pushed together with the same poles. If you hold the pen vertically, the resulting repulsion makes the top magnet float.
With diametrically magnetised ring magnets you can build sculptures. You can also combine them with other shapes, such as neodymium rod magnets.
