Uses for neodymium ring magnets:

Manufacturing and heavy industry use many types of ring magnets. School projects, arts, and craft industries and shopfitting companies use magnets for hidden fasteners in many of their outdoor advertising signs, including the sliding banner signs often installed near bus stops, and fixed roadside billboards. Changing individual signs within these scrolling and unscrolling advertising is made simpler and quicker with magnetic fasteners. Neodymium ring magnets act as the connective tissue in these arrangements without damaging the underlying material because the magnetic holding power is transferred through materials, without breaching the material itself. This allows advertisers to choose from a wider range of banner material than may be the case with clips or staples which may tear or damage the sign.

  1. Good Review by lan

    Small and powerful plus good service (Posted on 8/7/2019)

  2. sad Review by jus

    So bought these expecting sizes to be as stated. In general I've found most magnets have a slightly larger tolerance rather than smaller. For my use I needed the minimum 6mm I'd but they were actually 5.80mm so didn't suit my needs. While sizes weren't right, AMF didn't hesitate to refund me instantly hence the 4star rating. So buy with confidence but don't be disappointed if sizes vary a little.

    AMF Magnetics reply: Hi Jus, thank you for your feedback! Most of our magnets have a tolerance rating of +/- 0.05mm so it's unfortunate these magnets didn't suit your application! Please don't hesitate to get in touch regarding sizing in the future. (Posted on 8/7/2019)

  3. Cabinet latches Review by Flemming

    We are using these (a north and south pair) as the latching system in cupboards. By rebating them into the timber frame they have zero intrusion into the opening space (unlike most conventional latches). They do the job perfectly. (Posted on 6/6/2019)
