Neodymium Ring Magnets Custom Magnet | Fullzen Technology

Short Description:

Three-layer electroplating process, strengthens anti-rust and anti-corrosion, strengthens magnet strength, and reduces brittleness.

Small size, large use: keys, iron products and other adsorption storage, DIY, refrigerator magnet DIY, wardrobe door suction, locker suction, whiteboard magnet.

Round magnet with holes, axial magnetization, size diameter 12mm, thickness 3mm, hole diameter 4mm, can be fixed with screws.

Magnets are made from rare earth raw materials by burning paper, not iron. It’s fragile. Care should be taken to avoid impact, damage or pinch during operation.

    What is the resistivity of NdFeB magnet?

    The resistivity of a neodymium iron boron (NdFeB) magnet can vary depending on factors such as the specific composition of the magnet and its processing. However, in general, neodymium magnets have relatively low resistivity compared to non-metallic materials. The resistivity is typically on the order of microohm-meters (μΩ·m) or lower.


    Here's a general range for the resistivity of NdFeB magnets:

    Neodymium magnets: Approximately 5 to 10 microohm-meters (μΩ·m) or lower.

    What is the major disadvantages of NdFeB?

    Neodymium iron boron (NdFeB) magnets offer numerous advantages due to their exceptional magnetic properties, but they also have some significant disadvantages. Here are the major disadvantages of NdFeB magnets:

    Brittleness and FragilitySusceptibility to CorrosionTemperature SensitivityHigh Oxidation PotentialCostEnvironmental ConcernsHealth and Safety RisksDisposal Challenges.

    Is NdFeB a rare earth magnet?

    Yes, NdFeB is rare earth magnet.
