Neodymium N38 Magnets - Disk, 5x3mm

Magnets, often referred to (by our writer) as magical materials that move metals, are quite amazing materials that are used in a surprising number of different appliances and devices that you probably have in your own home. In fact, magnets often appear in even the most mundane electrical and Electronics devices and appliances, as well as for mechanical applications like cupboard doors and cutlery holders.

These magnets are N38 Neodymium Magnets, and are Disk-shaped with 5mm diameter and 3mm thickness, sold in packs of 5 to ensure double the magnet fun. The N38 rating means that, while these are still some of the strongest magnets available to hobbyists, there are still even higher ratings that are even stronger in terms of Residual Flux Density (Br) and Max Energy Product (BH) Max. However, despite these fancy scientific terms, all you need to know that these Magnets offers an impressive level of holding power, with a temperature resistance of up to 80°C, making it a great choice for most magnet applications.

Please Note: These magnets are priced individually but sold in minimum quantities of 5. This is done to reduce the overall cost for you, while making it easy to estimate exact pricings for each project.

Typical Applications for Neodymium N38 Disk Magnets:

Because of the somewhat standardised sizing of these magnets, they are an excellent choice for all kinds of applications from latches on doors and lids all the way through to building your own magnetic “Gauss Rifle”. They are also strong enough to be used as “screw-grabber” tools, which is a common application with these sized magnets, using a magnet on the end of a rod or wire in order to get screws out of confined spaces like engines or behind heavy machinery. And while they may not have the extreme strength of our N50 Neodymium Magnets, this can play into the strengths of these tiny magnets with a small but powerful magnetic field for precision applications.
