These Small Neodymium block magnets are little bigger than a watch battery but have an astonishing pull of 21.81lb. Every magnet has a triple coating of Nickel, copper and Nickel again to prevent against corrosion. Our Neodymium magnets are typically used in computer hard drives, audio speakers, electronics and medical fields. They also have many uses in engineering and manufacturing where small size and maximum strength are required. What's more, they are ideal for creating a shock-absorbing or damping effect because of their resistance to demagnetization.
