8mm diameter rod magnets are compact but surprisingly strong. magnetized through their thickness, these strong neodymium rod magnets are capable of producing a magnetic pull between 2.5kg (5.51lbs) and 2.7kg (5.95lbs). These magnets have many uses in engineering and manufacturing where small size and maximum strength are required and because of their resistance to demagnetization they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets.
