Here Is How To Glue a Disc Magnet - Easy Explanation

After discovering all of the many ways that disc magnets can be used in everyday life, both for household and commercial use, I wondered how these types of magnets are attached to things most effectively. So, I decided to do some research to come up with an easy explanation of how to glue a disc magnet.

How can you glue a disc magnet? To glue two disc magnets together, you will need to connect the opposite poles with the right kind of glue. The entire process will include cleaning off the surfaces and scratching them for the tightest hold possible.

Most people would be surprised to learn how they might use disc magnets in their everyday lives, whether they are at home or work. Disc magnets come in a variety of different sizes and can be found in most public places without being immediately noticed.

If you have ever wondered how these types of magnets are assembled to be used for these purposes around the world, keep reading this quick guide on how disc magnets are glued before being used.

How To Glue Disc Magnets

How To Glue Disc Magnets To Each Other:

1. Make sure both surfaces are clean and free of debris
2. Scratch the surfaces
3. Choose the correct Glue
4. Apply the glue to one of the magnet’s surfaces
5. Stick them together and wait for them to dry

In order to glue two disc magnets together, you will need to first begin by making sure both of the surfaces are clean and free of any debris.

If there is any kind of obstructive material on either side, it could cause problems for you when you begin the gluing process. So, before any of these materials are applied to the magnets, you will want to make sure everything is out of the way first.

Next, you will need to scratch the connecting surfaces to create friction and a better grip between the two magnets. This can be done with something sharp such as a nail or a screw. The scratches should go in all directions, and the surface of the magnet should look completely scratched up when you are done.

Another step to follow before applying the glue is to make sure that you are choosing the correct glue for this purpose. The best types of glue will be outlined in the next section, but here is a quick list of glues that you should stay away from at all costs when it comes to gluing disc magnets.

Glue To Avoid For Disc Magnets:

  • Hot glue gun
  • Any kind of glue that exhibits high temperatures

Due to the fact that most disc magnets are made up of the chemical element neodymium, you will always want to avoid any kind of glue that gives off high temperatures.

If the neodymium comes in contact with anything hot, it can potentially react tot he heats very negatively, and it can potentially become dangerous if you are not aware of this pairing.

So, if you naturally reached for your hot glue gun to begin this process, you will want to put it away and choose a different type of glue from the list of ideal magnet glues that are outlined in the next section.

Once you have chosen the right kind of glue for this project, you will apply a small amount to the middle of the flat surface of one of the magnets.

Immediately after this step has been completed, you will connect the magnets together and firmly press on them to secure their position, making sure they are evenly connected all the way around.

After leaving your magnets in a safe area to dry for a few hours to a whole day, you will have successfully glued your disc magnets together.

The Best Glue For Attaching Disc Magnets

As outlined in the process above, the act of gluing disc magnets together will obviously require the use of some type of glue or bonding agent.

While following the steps of cleaning and scratching the surface before connecting your two disc magnets to each other, you will want to make sure that you are using the best kind of glue for this purpose.

The list down below will give you a quick reference on the best types of glue that are ideal for attaching two disc magnets together.

The Best Glue For Attaching Disc Magnets:

  • Two-part Expoxy
  • Cyanoacrylate
  • Gorilla Glue (or any Urethane adhesive)
  • JB Weld
  • Liquid Nails
  • Mod Podge
  • Silicone Adhesives

The most ideal glue types and brands for attaching disc magnets, in particular, are two-part epoxy, also known as 5-minute expoxy, as well as any other type of epoxy glue that you can find at your local store.

Additionally, you can use cyanoacrylate, which is another name for super glue or crazy glue, as well as JB Weld, Liquid Nails, Mod Podge, and Gorilla Glue, along with any other type of Urethane adhesive.

Silicone adhesives will also work for attaching two disc magnets to each other. Most of these types of glue that have been listed and described are able to be found at you local hardware, specialty craft, or even grocery store for a decent price.

Regardless of the reason, you are trying to connect two disc magnets together, one of the most important things yo consider is the quality of glue that you are using to bond them. The action of gluing the magnets together will have no point if they just end up coming apart in the near future.

Which Sides Of Disc Magnets Can Be Connected?

While the process of gluing two disc magnets together is rather quick and simple, as outlined in the first section of this article, there is one small problem that you could run into during these steps.

Even though it is very easily fixable, you will need to be aware that there is only one certain side of two disc magnets that are able to be connected together.

This is due to a concept in magnetics that is called polarity. Basically, all magnets have both a North and South Pole, which is the direction in which their magnetic field extends on either side.

The most basic rule of a magnet’s polarity is that opposites attract. So, you will need to be aware of where each pole on both of your magnets is located.

In order to flawlessly connect and glue together your disc magnets, the opposite poles, North and South, must be touching with the glue between them.

Magnet Polarity Recap:

  • North and South facing poles of attraction
  • Opposite sides attract
  • Same sides repel

Whether you decide to find out the polarity before you begin your project for an easier time, or you go with trial and error, you will have a very hard time connecting the same poles together, which should be a clear giveaway of the correct method of gluing the two.

How can I tell the polarity of my disc magnets?

The easiest way to tell the polarity of a disc magnet is to hold it up on its side next to a compass on a flat surface. The South point of the compass will point to the North Pole while the North point will indicate the South pole.

What is another way to find the polarity of a disc magnet?

To find the polarity of a disc magnet, you can use something called the floating method. To properly test it this way, you will simply pour some water into an open cup or bowl, placing a piece of styrofoam on the water with the magnet on top of it. The magnet will spin around until its North Pole is facing the northernmost direction.
