Ferrite Magnet - FIRST4MAGNETS - 60mm x 20mm x 15mm - Pack of 2

The maximum pull force is approximately 4.9kg. This is achieved when the magnet is in direct, flush contact with a clean, mild steel surface of equal thickness.

Yes, ferrite magnets have excellent resistance to corrosion and do not require special coatings, making them suitable for many outdoor applications. However, prolonged exposure to harsh weather conditions should be considered.

Yes, these magnets can operate effectively in temperatures up to 180°C without significant loss of magnetic strength.

Ferrite magnets are more economical and offer better corrosion and temperature resistance, but have a lower pull strength. Rare earth magnets (like neodymium) are much stronger but are more expensive and sensitive to heat and corrosion.

Store magnets with opposite poles facing each other or use a keeper (a piece of steel) to bridge the poles. This helps maintain their magnetism and prevents them from attracting unintended objects or chipping.

For light doors or cabinets, they might suffice. However, for heavier doors, their 4.9kg pull strength may not be sufficient on its own. Consider the weight and required holding force for your specific application.

Each magnet measures 60mm in length, 20mm in width, and 15mm in thickness.

Ensure the metal object is made of a ferromagnetic material (iron, nickel, cobalt). Verify the magnet is in direct contact with the surface and that the surface is clean. Check if the object is too heavy for the magnet's 4.9kg pull strength.

Handle magnets with care. Avoid dropping them or allowing them to slam together. Store them properly with protective material between them if storing multiple magnets.

Ferrite magnets have excellent resistance to demagnetization. Ensure the magnet has not been exposed to extreme heat (above 180°C), strong opposing magnetic fields, or physical shock.
