Q & A

Q1. Are n52 block magnets suitable for outdoor use?

A1. Yes, they are. These block magnets have a coating of electroplated Ni-Cu-Ni for optimal corrosion resistance. Users should note that although the coating offers excellent protection against rust and corrosion, prolonged exposure to harsh outdoor elements may gradually wear the coating.

Q2. What are the recommended storage methods for N52 block magnets?

A2. Users are advised to store these magnets in a dry and cool environment, ideally at room temperature. They should keep them away from direct sunlight, as this may affect the coating. Further, users should stack them using ferromagnetic spacers between the magnets to prevent them from chipping or scratching.

Q3. Can block N52 magnets attract large metallic objects?

A3. Yes, they can. The N52 block magnets are designed to have a powerful magnetic hold. This enables them to attract and stick to large metallic objects. However, the strength with which the magnet holds will depend on multiple factors. These include the size, thickness, and material type of the magnet and object. Additionally, the magnetic surface area contact, object orientation, and environmental vibration will also affect the hold.

Q4. Do block N52 magnets lose their magnetism with time?

A4. No, they don’t. Neodymium magnets are designed to last several years and even decades under optimal storage conditions. However, conditions such as extreme heat exposure, direct sunlight, and physical damage may cause loss of magnetism over time. N52 is the strongest magnet. Assuming all conditions are optimal, it can last up to 100 years.

Q5. Can N52 block magnets be stacked to increase their magnetic strength?

A5. Yes, they can. Stacking N52 block magnets increases their magnetic strength. However, they should be separated by small, non-magnetic spacers. These allow the magnetic fields to interact. Users should avoid stacking them directly against one another. This will result in fields cancelling each other out.
