Description
A 4 x 3mm neodymium magnet refers to a small, disc-shaped magnet with a diameter of 4mm and a thickness of 3mm. Neodymium magnets, also known as NdFeB or NIB magnets, are made from an alloy of neodymium, iron, and boron. These magnets are known for their exceptional strength despite their small size, making them ideal for various applications including electronics, industrial uses, and crafting.
Here are a few characteristics of 4 x 3mm neodymium magnet :
- Strength: Neodymium magnets are among the strongest types of permanent magnets available, with a high magnetic field strength.
- Durability: They are brittle and can chip or break if not handled carefully, but they maintain their magnetic properties well over time.
- Coating: They are often coated with nickel, zinc, or epoxy to protect against corrosion and physical damage.
- Temperature Sensitivity: Their magnetic properties can be affected by high temperatures, so they are best used in environments where temperature fluctuations are minimal.
Applications:
- Electronics: Used in hard drives, speakers, headphones, and other electronic devices.
- Industrial: Employed in magnetic separators, motors, and sensors.
- Crafting and DIY Projects: Popular for holding items together, making magnetic clasps, and other creative uses.
