• Magnetization: Axially magnetized (Poles on the flat circular faces)
• Surface Gauss: Approx. 5,233 Gauss

Material Description:

Our 20x10mm N52 discs are engineered for applications where an incredibly deep and powerful magnetic field is required. The 10mm thickness creates a massive magnetic volume that can penetrate through thick non-magnetic barriers like heavy structural timber, thick industrial plastics, or composite housings. These are the premier choice for heavy-duty hidden latches, industrial magnetic separators, and securing heavy machinery or tools in high-vibration environments.

Handling Advice: EXTREME DANGER: These magnets are exceptionally powerful. With nearly 30 lbs of pull force, two magnets will jump together from a significant distance with enough speed to shatter the brittle core or cause serious injury to fingers (crushing or blood blisters). Always handle one at a time and use non-magnetic spacers. Never let them snap together or onto steel surfaces.

Warnings and Safety Information:

• Crush Hazard: High risk of serious skin and finger injury. Handle with industrial-strength focus.
• Choking Hazard: Keep strictly away from children and pets.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants at all times.
• Electronics: Keep well away from hard drives, credit cards, and sensitive electronic testing equipment.

Applications:

• Heavy-duty magnetic stirrers for ultra-high-viscosity industrial chemistry
• Concealed structural latches for heavy secret doors, thick panels, and security safes
• Industrial-strength tool organization and heavy equipment mounting
• High-torque magnetic couplers and rotors for professional robotics or wind turbines
• Magnetic separation systems for removing ferrous contaminants from bulk materials
