Usage & Safety Guide: Neodymium Magnets

Operating Temperatures & Heat Exposure 

What You Need to Know:

Neodymium magnets are highly resistant to demagnetization under normal use, but their strength can be affected by heat. Here’s what you should consider:

• Normal Operating Range: These magnets work best between -20°F (-29°C) and 176°F (80°C). Using them within this range ensures no noticeable loss of strength.
• Short-Term Heat Exposure: If exposed to temperatures between 177°F (80.5°C) and 300°F (149°C) for 10–15 seconds, they may experience a gradual, permanent reduction in magnetic strength.
• Critical Heat Exposure: Temperatures above 590°F (310°C) will completely demagnetize the magnet, rendering it useless.

Takeaway for Customers:

Always ensure magnets are used within their recommended temperature range. Avoid exposing them to high heat environments like ovens, welding areas, or direct flames.

Gauss Readings for Air Transport

What You Need to Know:

Magnets can interfere with aircraft navigation systems if their magnetic field strength exceeds certain limits. The U.S. Department of Transportation (PHMSA) has strict guidelines for transporting magnets by air:

• Packages with a magnetic field over 0.00525 gauss at 15 feet from any surface are considered restricted.
• If the field strength at 7 feet is less than 0.002 gauss, the package is not classified as “Magnetized Material.”

Test Results for Adamar Magnets:

• Single magnet at 15 feet: 0.0010–0.0015 gauss (safe for air transport).
• Four magnets at 15 feet: 0.0015–0.0020 gauss (still safe).
• On/Off magnets in "off" position: 0.0010–0.0015 gauss (safe).

Takeaway for Customers:

Adamar magnets are tested to comply with air transport regulations when packaged correctly. If you plan to ship magnets via air, ensure proper packaging and labeling.

Pacemaker & ICD Safety Information

What You Need to Know:

Strong neodymium magnets can interfere with pacemakers and ICDs (Implantable Cardioverter Defibrillators). Exposure to a magnetic field above 10 gauss (1mTesla) may alter device function.

Safe Distances from Adamar Magnets:

• For most Adamar magnets, staying at least 12–18 inches away is recommended.
• On/Off block magnets in "off" position produce negligible magnetic fields and are safe at close distances.

Takeaway for Customers:

If you have a pacemaker or ICD, consult your doctor before using magnetic tools or devices. Always maintain a safe distance of at least 12–18 inches from active magnets.

Cell Phones & Magstripe Cards Safety Information

What You Need to Know:

Magnets can affect magstripe cards and certain phone features:

• Credit/Debit cards can be damaged by fields above 4000 gauss.
• Hotel key cards can be affected by fields above 300 gauss.
• Cell phones are generally unaffected, but their built-in compass may temporarily malfunction near strong magnetic fields.

Safe Distances from Adamar Magnets:

• For most Adamar magnets, keeping devices and cards at least 12 inches away is recommended.

Takeaway for Customers:

Store your credit cards, hotel key cards, and phones away from strong magnets to avoid damage or interference with functionality.

Key Points Summary

1. Use magnets within their operating temperature range (-20°F to 176°F) to avoid loss of strength.
2. Adamar magnets comply with air transport regulations when packaged correctly.
3. Maintain safe distances from magnets if you have a pacemaker or ICD (12–18 inches).
4. Keep magstripe cards and phones at least 12 inches away from strong magnets to prevent damage or interference.
