How-To Glue a Disc Magnet on to Metal - This Should Be Easy!

After reading through a tutorial for gluing two disc magnets together for a small craft project recently, I wanted to know if it was possible to glue a disc magnet onto a metal surface. So, I did some research to find out that the process is actually very simple. Follow along with this easy guide to find out how you can do it too!

How do you glue a disc magnet onto metal? In order to glue a disc magnet onto a metal surface, you will first need to make sure that both areas are clean and the surface of the magnet is scratched to give it a better grip. Once you have chosen the correct glue for your project, you will apply a small amount to the scratched side of the magnet, connecting it to the metal surface. 

Regardless of your reasoning behind gluing a disc magnet to a metal surface, you will find that it is not something that is hard to do. By just following a few simple steps, you will be able to successfully attach your magnet to the piece of metal of your choice with little to no problems, as long as you choose the correct materials.

How To Glue a Disc Magnet On To Metal

If you ever find yourself needing to permanently attach a disc magnet to any kind of metal, you will be able to do so seamlessly by following the steps that are outlined below. Whether you are doing a small craft project or trying to build your own tool of some kind, you will have great success in no time.

Materials Needed:

  • Disc Magnet(s)
  • The metal surface of your choice
  • Glue adhesive of your choice
  • Screw, key, or something similar
  • Damp towel with hot water

The basic materials that you will need to connect a disc magnet and metal will most obviously be the disc magnet and the metal surface that you will be gluing together.

Additionally, you will need to have a damp towel with hot water on hand, as well as some kind of sharp objects like a screw, key, or something similar, as well as the glue adhesive of your choice.

The actual steps of gluing a disc magnet onto metal are outlined in the organized list below.

How To Glue a Disc Magnet On To Metal:

  1. Clean the surface of the magnet and metal
  2. Scratch the surface of the magnet that will be attached
  3. Choose your glue
  4. Apply the glue to the center of the magnet
  5. Place the glued side onto the metal surface
  6. Apply pressure for at least 1 minute
  7. Allow the area to dry

To begin, you will need to make sure that both surfaces that you are connecting are clean and free of any obstructive objects or debris. This can be done by using a damp towel with hot water to wipe off the magnet and the metal surface.

Next, you will want to scratch the surface of the magnet to create some kind of friction for when it is attached permanently. This will prevent the magnet from sliding down on the surface since both the magnet and metal are likely to be very smooth in texture.

This can be done by using some kind of sharp point that is found on a metal object. These objects can include a loose screw, nail, key, or even a bent paper clip that has a sharp point on the end.

Once you have scratched up the entire surface of the magnet that will be directly connecting to the metal, you will need to choose the correct type of glue that will be best for this purpose.

If you are unsure of what type of glue will be ideal for this situation, you can keep reading on to the next section for a more detailed guide on this specific part of the process.

After choosing the glue, you will place a small dot onto the middle of the scratched surface of the magnet, pressing it onto the metal firmly. This should be held for at least 1 minute, minutes, and the entire area should be left to dry for an additional day.

The Best Glue To Use For Disc Magnets And Metal

When it comes to gluing a disc magnet to any kind of metal surface, you will want to make sure that you use the correct type of glue. There are certain errors that can be detrimental to your project and the functions of your magnet.

For instance, you will always want to stay away from any kind of glue that has the heat on it. Hot glue guns will expose your disc magnet to temperatures that are too high, and can possibly cause it to stop working overall.

Now that you are aware of the type of glue that you should not use for your disc magnets, you should be informed of some great glue recommendations that will help you come out with a successful project.

The Best Types Of Glue To Use For Disc Magnets:

  • Gorilla Glue
  • Super Glue/Crazy Glue
  • Mod Podge
  • Two-part Expoxy
  • Cyanoacrylate
  • JB Weld
  • Liquid Nails
  • Silicone Adhesives

When it comes to attaching a disc magnet to any kind of surface, you will want to go with any of the options that are listed above. For a strong and long-lasting connection, you can’t go wrong with any of these brands and glue types.

Does It Matter Which Side Is Glued Onto The Metal?

In the world of magnetism, there is a term called “polarity” that refers to the direction in which the magnetic field of a magnet faces, as well as what types of materials it attracts.

This can be anything from certain types of metal objects to other magnets. Depending on the direction of the magnetic fields, or “poles”, a magnet might stick to an object on one side, while it completely repels it on the opposite side.

This is due to the fact that opposites attract when it comes to magnets. So, the North Pole of a magnet will be attracted to the South Pole of another object, while both North Poles will not be able to be connected because the magnetic field is keeping them separated so strongly.

Disc Magnet Polarity:

  • The direction of magnetic fields
  • North and South “Poles”
  • Opposite poles attract
  • Can pull or repel objects

So, how does this affect the process of gluing a disc magnet onto a magnetic surface? The answer to this question is that it will depend on the type of metal.

For instance, if the metal you are trying to glue the magnet onto is a material that would normally be attracted to it, you might have a problem while trying to connect a certain side of the magnet to the surface.

However, this problem can be fixed with a simple trial and error. In other words, if you attempt to attach the magnet on one side and it pulls itself back, you can simply flip it onto the opposite side.

As you can see, disc magnets are some of the most versatile magnets that exist in the world. With the wide variety of uses that they come with, they can also be attached to metal surfaces with glue for added functionality.

With the combination of the right materials and a few careful steps, you will be able to seamlessly attach your disc magnet to another piece of metal with virtually no problems.
