1" (25.40mm) OD X 0.750" (19.05mm) ID X 0.500" (12.7mm) thick, SmCo28 Rare Earth Samarium Cobalt Ring Magnet, Magnetized through the thickness, not plated.
Rare Earth Samarium Cobalt Ring Magnets can operate in high temperature environments, or in an application where a demagnetizing force is present. Samarium Cobalt Magnets are typically used in high temperature motors, aerospace and military applications.
Ring Magnets can be custom manufactured in different ways so that they can be magnetized in a specific direction. Below is an overview of the different direction of magnetization options, however, the direction of magnetization can only be set during the manufacturing process and cannot be changed once the magnet is made.
Through the Thickness: Ring magnets where a magnetic field travels from the ID of the ring magnet to the OD of the ring magnet.
Through the Diameter: Ring magnets where a magnetic field flows from the OD of the “north pole” to the OD of the “south pole”. The ID of the ring magnet will have a magnetic field that is straight and crosses uniformly across the ID.
Radially Magnetized: Radially magnetized ring magnets have the magnetic poles on the OD / ID instead of the face. Radial magnets are made as a single piece or in multiple pieces depending upon the size of the magnet. A list of radial rings is available under our Radial Ring magnet section.
Multi-Pole Magnetization on the Face: If a ring magnet is large enough it can be magnetized with multiple poles on the face in a North / South configuration. An example of a multi-pole ring is our part number R1050.
SM Magnetics, the engineering and manufacturing sister company of SuperMagnetMan, has been assisting Corporate customers for many years with their custom ring magnet and magnetic assembly applications.
SM Magnetics works with Corporate customers to optimize their design and then manufacture the specific ring magnet or magnetic assembly to meet the required spec. SM Magnetics has their own ISO certified factories and controls the entire manufacturing process. For assistance from a technical representative at SM Magnetics, click here for the contact info.

If you encounter a problem with your order, or have questions and wish to return your parts, please contact us at 205-621-8841 or email@example.com to acquire a Return Material Authorization (RMA) number. All returns must be made within 60 days of delivery date. To ensure a return is processed quickly, an RMA number and a copy of the packing slip must be included with the shipment.
All returns should be sent to:
Attn: (RMA number)

Shipping Errors or Damaged Product
Shipping cost for returns will be the responsibility of the customer unless the parts are incorrect or damaged upon arrival. For shipping errors or damage, SuperMagnetMan will bear the cost to replace the parts and the return shipment for the incorrect or damaged product. Custom orders cannot be returned unless the parts are incorrect or damaged. For details on returning parts, contact our shipping department at 205-621-8841 or email firstname.lastname@example.org for instructions.
Parts returned at the discretion of the customer will be subject to a 10% restocking fee. This policy applies only to orders received from our online store.
If possible, please ensure that all products are in their original packaging to avoid damage during the return shipment. The customer will be responsible for shielding the magnets properly so that the box or envelope is not magnetic at the surface. If a paper clip sticks to any side of the package more packing material (sheet metal, foam wrapping, peanuts, etc.) or a larger box will be required. If the parts are not properly protected, there is no guarantee the return will make it back to us in its original condition, and a refund will not be issued.
If replacement parts are not needed, refunds will be issued for parts only once they are returned to our facility in the same condition they were shipped. This does not apply if the return is for incorrect or damaged parts.
It is important to us that you are happy with your order. Please contact us with any questions or concerns.
Thank you for your business!
Payment & Security

Magnet is strong enough for our purpose, however it is so fragile that it broke on the first jump to steel. We were able to glue and bandage it.
So sorry to hear your magnets became broken. But I am glad you were able to get use out of it still. It is a great magnet. Unfortunately this can happen when in contact with other metals. This material SMCO naturally is a very soft material. It does an incredible job for high heat applications.
