FAQ – JC Magnetics
1. General Questions
Q: What are neodymium magnets, and why are they so powerful?
A: Neodymium magnets, also known as NdFeB or rare-earth magnets, are the strongest permanent magnets available. They are made from a combination of neodymium, iron, and boron, which gives them an extremely high magnetic strength.
Q: What is the difference between N35, N52, and other neodymium magnet grades?
A: The N-rating refers to the magnetic strength of the magnet. N52 is the strongest commercially available grade, while N35 is weaker but more affordable. Higher grades provide stronger magnetic fields but may also be more brittle.
Q: What coatings are available for neodymium magnets, and which one should I choose?
A: Neodymium magnets are prone to corrosion, so they come with various coatings like nickel, epoxy, gold, and zinc. Epoxy-coated magnets offer better protection against moisture, making them ideal for humid environments.
2. Shipping & Orders
Q: Why haven’t I received my password reset email?
A: Sometimes, the password reset email may go to your spam folder. Please check your spam/junk folder and mark our emails as "Not Spam" to ensure future messages reach your inbox. If you still haven’t received it, contact our support team.
Q: How long does shipping take?
A: Shipping times depend on your location and selected shipping method. Orders are typically processed within 1-2 business days, and standard shipping takes 2-6 business days.
3. Using Neodymium Magnets
Q: Are epoxy-coated N52 magnets less likely to crack?
A: Yes! Epoxy-coated magnets offer an extra layer of protection, making them less brittle and more resistant to chipping compared to uncoated or nickel-coated neodymium magnets.
Q: How do I safely separate strong neodymium magnets?
A: Strong magnets can be difficult to separate. The best method is to slide them apart instead of pulling directly. Using a plastic spacer can also make separation easier.
Q: Why do neodymium magnets break so easily?
A: Neodymium magnets are incredibly strong but also brittle. This makes them prone to chipping, cracking, or breaking if they collide forcefully or are dropped.
4. Applications & Industry Use
Q: What are neodymium magnets used for?
A: Neodymium magnets have a wide range of applications, including:
- DIY & crafts
- Engineering projects
- Industrial machinery
- Magnetic therapy
- Magnetic closures in consumer products
- Eyewear toppers
Q: Can neodymium magnets lose their magnetism over time?
A: Under normal conditions, neodymium magnets retain their magnetism for decades. However, exposure to extreme heat (above 80–200°C, depending on the grade) or strong opposing magnetic fields can reduce their strength.
