Working with Neodymium Magnets

Magnets are essential for many projects—whether it be home improvement or a component of a product you are selling. In some cases it is necessary to glue them. Below are some tips that may ensure your success the first time around. Application Tips: Make sure to read the instructions of the adhesive you’re using.  Clean the surfaces you’re going to apply the adhesive to. Residue, grease, or dirt can create an unnecessary barrier that doesn’t allow the glue to take hold as intended. Isopropyl alcohol or similar will do the trick. Many epoxies and adhesives suggest roughening the smooth surface you...

The north and south poles of a magnet are equally strong. The strength of a magnet refers to the ability of the magnet to produce a magnetic field and to attract or repel other magnets or magnetic materials. A magnet's strength is independent of its magnetic pole.  In general, the strength of a magnet is determined by its material and the shape of its magnetic field. The magnetic field is the area around the magnet in which the magnetic force is present. The shape of the magnetic field can affect the strength of the magnet, as can the size and shape...

Neodymium magnets are attracted to ferromagnetic materials, which are materials that are capable of being magnetized and are attracted to magnets. Ferromagnetic materials include iron, steel, nickel, cobalt, and some alloys of these materials. Neodymium magnets will also attract other rare earth magnets, such as samarium-cobalt magnets and cerium-iron-cobalt magnets. Neodymium magnets will not attract non-ferromagnetic materials, such as copper, aluminum, gold, and silver.  It is worth noting that the strength of the attraction between a neodymium magnet and a ferromagnetic material will depend on the specific properties of the magnet and the material, as well as the distance between...

The answer is yes! By adding one disc magnet or block magnet on to the other, e.g. stacking, the stacked magnets will work as one bigger magnet and will exert greater magnetic performance. This does not apply to cylinder magnets and sphere magnets.Two identical disc or block magnets stacked together are almost twice as strong as one magnet as long as the thickness of the stack does not exceed the width/diameter of the stack. The taller the N-S N-S N-S stack is, the more intense the magnetic field at the end of the stack will be. However, the magnetic field,...

You'll likely want to experiment with different magnets to get just the right one. Ultimately you will need to know the size, shape, and strength or pull force. Hopefully, the following tips will help reduce the often-inherent trial and error process. Do Some Research For advice on DIY projects or other crafts (hanging signage/artwork, scrapbooking, jewelry, magnetic spice racks etc), you may find valuable advice online from other individuals who have already done some of the homework for you. Estimate the Exact Size and Shape You Need Start with estimating the footprint or area your magnet will be placed into or used for.Do...
