Rare earth magnets are the strongest type of permanent magnet currently made. They produce an astonishing pull of 18lb and every magnet has a triple coating of nickel, copper, and nickel again to prevent corrosion. They are commonly used in creative applications such as models and theatre design, furniture making, exhibition stands, and packaging. Their resistance to demagnetization makes them ideal for creating a shock-absorbing or damping effect when used to repel other magnets.
