Realth Magnets Disc Neodymium Strong Permanent Rare Earth Magnetic for Fridge Office Science Project Building and Craft 12 Pack(MC20212)
What Are Neodyminum Magnets? Neodymium magnets are also called rare earth magnets, and they are known to be the most powerful type of permanent magnets. They are moderately priced, allow for dimensional reductions, and offer the best value when comparing performance, size and cost. While Neodymium magnets have good resistance to external demagnetization fields, they are not very resistant to corrosion. Neodymium magnets are also sensitive to heat and can lose a fraction of their magnetic strength at temperatures above 80°C. Due to this, they have to be coated with nickel to make them corrosion resistant. Since Neodymium magnets are so strong and powerful, they need to be handled with proper care. Neodymium magnets can pinch very hard, and some of our larger magnets will easily break bones. For you own safety do not allow fingers or any part of your body to come in between the magnets, Handle with Extreme Care. Thick gloves and goggles are advised when handling larger magnets. ALWAYS KEEP MAGNETS AWAY FROM CHILDREN AND KEEP AWY FROM OTHER MAGNETIC E-DEVICES. Why Magnets Break Easily? Misconception It’s easy to assume that these magnets should be as strong as steel, especially with their shiny, metallic, nickel plated surface. Unfortunately, that assumption couldn’t be further from the truth. Magnets are not ductile like common metals Many common metals are fairly ductile. If a material is ductile, that means you can bend or reshape it before it breaks. Steel or aluminum are ductile metals. This isn’t true for non-ductile materials like glass or ceramic. You can’t bend a ceramic coffee mug! If you try bending a neodymium magnet, it breaks. Neodymium magnets are more like a ceramic than a piece of steel. Don't allow magnets to hit each other Just two magnets attracting towards one another are less likely to break than one magnet attracting to a big stack of magnets. The stack of magnets provides greater magnetic attraction, increasing the impact speed and the chances of failure. How to Avoid Breaking? Slide one magnet off the top of the stack. Once off the stack, carefully start lifting the magnet. Do not allow Neodymium magnets to snap together with full force or they may chip or break. Always have a bumper like plastic or rubber before you stacking 2 magnets for easier removal. Do not attempt to machine or drill the magnets.
