Magnetic disc 4mm diameter, thickness 3mm, N35

Neodymium disc magnets of 4mm, 3mm thickness, nickel-plated. Magnetization N35 axial (parallel to height), Strenght approx. 400gram. 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 neodymium disc magnet has a 4 mm outer diameter and a 3 mm thickness. It’s a compact size for precise mounting and small parts.
How strong is the magnet in practical use?
The holding force is approximately 400 g under ideal conditions. Real-world results depend on the contact surface, alignment, and the material being held.
Which side is magnetic, and how are the poles oriented?
The magnet is axially magnetized, meaning the poles are on the two flat, round faces. The curved side is not a pole face.
How do I separate two magnets safely?
Slide them sideways apart instead of pulling them straight apart. This helps prevent sudden snapping, which can chip or break the magnets.
Does this magnet have a countersunk hole for screws?
It’s supplied as a standard disc magnet. For screw mounting, you can use suitable holders, brackets, or adhesive solutions depending on your setup.
What surfaces does it work best on?
It performs best on clean, flat ferromagnetic surfaces like steel. Thin paint layers, curved surfaces, or gaps can reduce holding performance.
What is the coating and why does it matter?
It has a nickel-plated finish that offers a durable surface and helps protect the magnet. It also gives a smooth contact area for consistent placement.
Is this magnet suitable for model making and signage?
Yes, it’s commonly used for model making, hanging signs, and advertising displays. The small size makes it easy to integrate without adding bulk.
How should I clean and maintain the magnets?
Wipe them with a soft, dry cloth to remove dust or metal particles. Keeping contact surfaces clean helps maintain reliable grip and prevents scratching.
What does N35 mean for compatibility and performance?
N35 is the magnetization grade and indicates a solid performance level for general applications. It pairs well with steel surfaces and common magnetic mounting setups.
