Magnetic disc 4mm diameter, thickness 2mm, N45

Neodymium disc magnets of 4mm, 2mm thickness, nickel-plated. Magnetization N45 axial (parallel to height), Strenght approx. 420gram. Magnets attract or repel on a pole side. Our disc magnets are axially magnetized. This means that the poles are on the round side. In order to remove magnets from each other, you have to slide them away from each other. ATTENTION ! Because of the magnetic force they can collapse on top of each other and possibly break. Application: Is widely used in advertising applications, hanging signs and model making.

FAQ

FAQ

What are the dimensions of this disc magnet?
This disc magnet has a 4 mm outer diameter and a 2 mm thickness, making it a compact option for precise applications.
How strong is the magnet in everyday use?
The holding force is approximately 420 g under ideal conditions. Real-world performance depends on the surface material, thickness, and contact area.
What does “axially magnetized” mean for positioning?
The magnetic poles are on the flat round faces of the disc. This makes it ideal when you want the magnet to pull straight toward a surface.
How do I separate stacked magnets safely?
Slide them sideways apart rather than pulling them straight apart. This reduces the risk of snapping together and chipping.
Which surfaces work best for mounting?
Smooth, flat ferromagnetic surfaces typically give the best grip. For non-magnetic surfaces, you can pair the magnet with a steel counter plate.
Can I glue this magnet, and what should I keep in mind?
Yes, it can be bonded to clean, dry surfaces using a suitable adhesive. Keep the contact faces flat and avoid impacts during curing.
What material and coating does the magnet have?
It’s a neodymium magnet with a nickel-plated finish. The coating helps with durability and gives it a clean, professional look.
How should I clean and maintain the magnet?
Wipe it with a dry or slightly damp cloth and keep it free from dust and metal particles. Store it dry and handle it carefully to avoid chips.
Is this suitable for signage, advertising, or model making?
Yes, the compact size and reliable pull make it a practical choice for hanging signs, display work, and model building. It’s also easy to combine in sets for more grip.
Does this magnet have a countersunk hole for screws?
Mounting holes are not specified for this product. If you need screw mounting, consider using a holder or an alternative mounting method.
