Block magnets (87)
Neodymium block magnets combine a high holding force with a compact, rectangular format. The flat contact surface makes them convenient for mounting in slots and against flat surfaces. Here you will find versions ranging from a few millimeters for model making and electronics to large blocks for industrial use.
Which block magnet is right for your project?
- Small enclosures and model making: small, lightweight block magnets with a holding force of a few kilos.
- Cabinet doors, furniture and interior construction, motorhomes and caravans: flat, larger blocks with approx. 4 to 10 kg holding force.
- Workshop and assembly: powerful blocks for tools, dies and heavier panels.
- Industry and machine building: very powerful block magnets, also with a stainless steel handle.
- Screw-in mounting: versions with one or two countersunk holes, sometimes plastic coated. Pay attention to the polarity on the countersunk side.
- Gluing without drilling: self-adhesive block magnets for light applications.
- Damp environments or steel doors: epoxy versions. Read more about steel doors.

Good to know
The stated holding force is measured under ideal conditions on a flat steel plate; in practice, the actual holding force is lower. Read how holding force is determined or see the difference between holding force, pulling force and working load. Ordered and paid for before 16:00 on working days, it will be shipped the same day if in stock. Free shipping within the Netherlands from €45. Consumers have a 30-day cooling-off period.
Frequently asked questions
Which block magnet do I need for a cabinet door?
For a standard cabinet door or flap, a block magnet with approx. 4 to 10 kg holding force is more than enough, such as 30 x 10 x 2.5 mm or 30 x 13.5 x 5 mm with countersunk holes. Combine it with a steel counterplate or a second magnet.
Why are there block magnets with countersunk holes in north and south pole versions?
With a magnet with a countersunk hole, the pole on the countersunk side is fixed. If you want two magnets to close against each other, for example in a door and a frame, you need one north pole and one south pole version. Two identical versions will repel each other.
How do I attach a block magnet without a hole?
Glue it with a two-component adhesive, such as UHU Plus epoxy adhesive, clamp it in a suitable slot, or choose a self-adhesive version. First clean and degrease the surface.
Can I saw or drill a block magnet?
No. Neodymium is hard and brittle, and can break or splinter when machined; the grinding dust is also flammable. Therefore, choose a size that fits, or a version with a countersunk hole. More tips in How do you mount a magnet?
Can I use block magnets outdoors or in a damp room?
The standard NiCuNi coating is intended for dry indoor use. For damp environments, choose an epoxy coated or plastic coated version.
How do I safely remove a large block magnet?
Never pull straight up, but slide it sideways off the steel or another magnet. Wear gloves with large blocks and work with one magnet at a time: two large blocks can seriously pinch fingers.
Do you also supply block magnets to interior and machine builders?
Yes, a large part of our block magnets go to companies. You can order on account with a purchase order, receive volume discounts for larger quantities, and with a fixed annual volume we reserve stock for you. Business ordering.
