The Quick Magnet Buying Guide: Pick the Right One for Your Project

The Quick Magnet Buying Guide: Pick the Right One for Your Project

Magnets are critical to countless industries—but choosing the wrong type costs time and money. Here’s how to select the perfect magnet in 3 simple steps:

1. Choose the Right Magnet Type

◦ Neodymium (NdFeB): Strongest, best for EV motors, drones, and compact high-power devices. Needs plating (zinc/nickel) for corrosion resistance.

◦ Samarium Cobalt (SmCo): Ideal for high-temperature (up to 400°C) applications like aerospace equipment. Premium price but long-lasting.

◦ Ferrite: Budget-friendly, corrosion-resistant, great for fans, speakers, and basic sensors. Less powerful but cost-effective.

2. Check 3 Non-Negotiable Specs

◦ (BH)max: Higher number = stronger magnet (measured in MGOe).

◦ Working Temperature: Add a 20°C safety margin to avoid demagnetization.

◦ Coating: Match to your environment (epoxy for saltwater; nickel for dry use).

3. Smart Buying Tips

◦ Always ask for third-party test reports (SGS, ISO) to avoid counterfeits.

◦ Prioritize suppliers who offer custom shapes and fast delivery (7–10 days).

◦ Don’t overspec—low-grade neodymium (N35) works for most consumer products.
