4mm x 1mm Neodymium Disc Magnets N42 Super Strong Tiny Rare Earth Disk Magnets 4x1mm Small Round Magnets

These small, N42 grade cylinders are often used as triggering devices for Hall Effect sensors. They are also useful for small arts & crafts applications and tiny fridge magnets.

• 4mm diameter x 1mm height
• Each magnet’s north and south pole are on opposite 4mm diameter faces
• Each magnet can support a steel weight of up to 0.25kg vertically from the magnetic face when in flush contact with a mild steel surface
• 감자에 대한 탁월한 저항성
• 니켈 3겹 코팅, 구리와 니켈을 사용하여 부식을 줄이고 매끄럽고 깨끗한 마감 제공

These small Neodymium disc magnets are just 1mm thick which makes them ideal for craft and model-making projects. Plus, every magnet is coated with three layers of nickel, 구리와 니켈을 사용하여 부식을 줄이고 매끄럽고 깨끗한 마감 제공.

Our Neodymium magnets are commonly used in creative applications such as theatre design, clothes making, furniture making, exhibitions and packaging. They also have many uses in engineering and manufacturing where small size and maximum strength are required. What’s more, because of their resistance to demagnetisation they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets.
