Neodymium Ring Magnets

Powerful Neodymium Ring magnets can be purchased online from the wide range of Frenergy magnetic products which also includes a range of Block and Disc shaped Neodymium magnets. The product range contains Ring magnets in various grades of strength and in a range of width and height dimensions. Another unique and important consideration to take into account when selecting a Ring shaped magnet is the inside diameter(ID) measurement which indicates the diameter of the hole in the middle of the ring. The size of the central hole can be an important factor in determining which method of attachment is used for the magnet in your particular application. Common methods of attachment for all strong rare earth magnets to non-ferrous materials include epoxy glues, brackets and sewing the magnet inside or into soft furnishings or fabrics. Ring magnets can also be held in position with placement over pins or lugs with the same ID dimensions. Commercial products such as electronic devices may employ this method by using plastic casings or moulded synthetic covers with suitable lugs for the Ring magnet to fit over. The magnets are then often used to perform as a magnetic closure device or to operate as magnetic electrical switches. The magnetic aspects of these commercial products give these items a more modern or futuristic feel that appeals to consumers and in many cases, improves their performance. Hobbyists or home-based businesses often use timber or other non-ferrous materials to provide the round lugs that the ring magnet sits on. The magnets can then be used to bond component parts together or to make artistic creations compatible with ferromagnetic surfaces. Screws, tie wire and bolts through the central hole are also commonly used options for attaching the versatile Neodymium Ring Magnets.
