Working with Neodymium Magnets

The Best Way to Separate Strong Magnets

Instead of trying to pull them apart, firmly slide and/or twist them away from each other and far enough apart so that they don’t jump back together.Neodymium magnets are exceptionally strong. If you’ve never handled them before, you will probably be surprised by how powerful these magnets can be.This is because neodymium magnets are the strongest type of permanent magnet commercially available. In fact, they are far stronger than all other ceramic or alnico magnets of equal size – with a magnetic energy value as much as 18 times greater than these other magnets by volume and 12 times greater...

Can I solder or weld to neodymium magnets?

No. You cannot solder or weld to neodymium magnets. The heat will demagnetize the magnet and could cause it to catch fire.

What materials can I use to block/shield magnetic fields?

Magnetic fields cannot be blocked, only redirected. The only materials that will redirect magnetic fields are materials that are ferromagnetic (attracted to magnets), such as iron, steel (which contains iron), cobalt, and nickel. The degree of redirection is proportional to the permeability or density of the material.

What materials do neodymium magnets attract?

Ferromagnetic materials are strongly attracted by a magnetic force. The elements iron (Fe), nickel (Ni), and cobalt (Co) are the most commonly available and attracted elements. Steel is also very susceptible or attracted to a magnetic field because it is ferromagnetic as an alloy of iron and other metals.

What is the best way to work with self-adhesive magnets?

Self-adhesive magnets enable you to attach the magnet to a non-magnetic surface, such as aluminum, wood, plastic, ceramic, rubber, paper, and other non-ferrous materials. Normally, these magnets come in packs with half self-adhesive on the north side, and half with the self adhesive on the south side. This enables them to attract if needed to form a closure or fastener.  Our adhesive magnets are made with a foam based acrylic adhesive. This high-performance adhesive delivers excellent shear strength to resist slippage and edge-lifting. Simply peel the paper off the adhesive and stick it in position. You can quickly re-adjust it because the strong adhesive...

Adhesives, Glue and 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...

How do I pick the best magnet for my project?

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.Tip 1: 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. Tip 2: Try to estimate the exact size and shape of the magnet you will need.Start with estimating the footprint or area your...

How are steel strike plates and magnets used most effectively?

Steel discs (often called strike plates) offer added flexibility when working with magnets. They can be used in place of a magnet in some applications because they make an ideal target for other magnets to attract to and attach with. This can dramatically lower your production or project expenses as steel discs cost significantly less than magnets.Due to their ultra thin profile, these blank steel discs can be used to create a variety of magnetic catches, latches, packaging and box closure mechanisms – again, without the cost of an additional magnet. As a result, these discs are ideal for a...

Will stacking magnets together make them stronger?

Yes, stacking multiple magnets together can make them stronger. Two or more magnets stacked together will exhibit nearly the same strength as a single magnet of the combined size. For example, if you stacked two 1/2 x 1/4 inch thick disc magnets to make a 1/2 x 1/2 inch combined size, the two magnets would have nearly same strength as a single 1/2 x 1/2 inch magnet.

Is one pole, north or south, stronger than the other?

No, both poles of a magnet exhibit the same strength.
