These 40mm long blocks are incredibly powerful. Their strength and relatively low profile makes them perfect for holding up signs and other larger items. However, they can pinch quite hard if not handled with care, so use caution when working with these strong blocks.

These large, extremely powerful thin rectangular neodymium magnets are axially magnetized between the two 40mm x 30mm rectangular faces and provide an incredible pull force. Each magnet is coated with three layers of nickel, copper and nickel to give superior corrosion resistance and provide a smooth and clean finish. Our neodymium magnets have many creative uses plus they are widely used in engineering and manufacturing where small size and maximum strength are required. What’s more, because of their resistance to demagnetization they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets.
