About Diving Magnets

Diving Magnets (Pty) Ltd. was established in 2015 to supply the commercial diving industry with high-performance subsea magnets designed specifically for professional divers and offshore operations. Our products are engineered for use in demanding underwater environments where reliability, durability, and holding power are critical.

We specialize in industrial-grade neodymium pot magnets for commercial diving applications, providing divers with secure attachment points for tools, equipment, and operational tasks in subsea conditions. Our magnets are widely used by commercial dive companies, offshore contractors, marine service providers, and subsea inspection teams worldwide.

Standard magnets often deteriorate or lose strength when exposed to saltwater, moisture, and harsh marine environments. Our diver magnets are specifically designed to overcome these challenges through specialized protective coatings and robust construction, ensuring long-term durability and consistent magnetic performance even in extreme offshore conditions.

Based in Gordon's Bay, South Africa, Diving Magnets (Pty) Ltd. supplies customers globally with fast international shipping and reliable order fulfillment. Our online store continues to expand as we introduce new commercial diving tools and subsea magnetic solutions to meet the evolving needs of professional divers.

With over a decade of proven performance in demanding underwater environments, Diving Magnets has become a trusted supplier of professional-grade diver magnets used by contractors and diving teams worldwide.

Technical Specifications

Detailed engineering specifications for professional-grade diving magnets

Material Specifications

Neodymium Magnet

• Grade: N42 to N48 (High Performance)
• Composition: NdFeB (Neodymium-Iron-Boron)
• Coating: Epoxy - Polyethylene
• Coating Thickness: 15-20 microns
• Magnetization Direction: Axial (through thickness)

Steel Housing

• Material: AISI A3
• Corrosion Resistance: Excellent in saltwater
• Surface Finish: Brushed/Polished
• Housing Thickness: 2mm minimum

Eyebolt and Handle

• Material: 316 Stainless Steel
• Thread Type: Metric, Right-hand
• Minimum Breaking Load: 5x magnet pull force

Understanding Pull Force

Factors Affecting Performance

• Surface Condition: Rust, paint, or marine growth reduces pull force by 20-50%
• Material Thickness: Thin metal (under 5mm) reduces effective pull force
• Air Gaps: Even 0.5mm gap can reduce force by 50% or more
• Temperature: Higher temperatures reduce magnetic strength
• Pull Angle: Side pulling can reduce effective force by 70%+

Real-World Considerations

• Safety Factor: Use 2-3x rated capacity for dynamic loads
• Underwater: Current and wave action create additional forces
• Curved Surfaces: Reduce contact area and thus pull force
• Non-Ferrous Metals: Aluminum, brass, copper are non-magnetic
• Stainless Steel: Some grades (304, 316) have weak magnetic properties

Safe Handling And Maintenance Guidelines

Attaching

Note: Before placing the magnet, make sure the area is clean with no obstructions present.

1. With the magnet at a 45° angle, place the edge of the pot housing against the area where the magnet is intended to be attached.
2. Bring the handle part downwards while maintaining control of the pull force until the magnet is fully attached.
3. Before any load is applied, check that the face of the magnet is flush and in full contact with the ferromagnetic material with no obstructions.

Detaching

Detach the magnet by pulling upward on the rear end of the handle, away from the magnetic surface.

All working load must be applied through the eye nut only. The handle is designed solely to assist with controlled removal and positioning. Applying load to the handle instead of the eye nut may cause the magnet to release unexpectedly.

Always

• Always rinse magnets with fresh water after contact with salt water and remove any moisture directly afterwards.
• Always keep the surface of the magnet clean and remove any iron filings or small metal particles. Wipe frequently with a wire brush or rag.
• Always store magnets in a low humidity and mild temperature environment, away from sensitive electrical equipment.
• Always avoid collisions between magnets and heavy impacts against hard surfaces.

Do Not

• Do not test your magnet or hold it near a metal object — the pull force will move uncontrollably, causing pinch points, damage and demagnetisation.
• Do not drop or allow magnets to collide with hard surfaces or other magnets — this causes damage to personnel, magnets and demagnetisation.
• Do not test your magnet by hanging from or underneath it — the magnet can detach and may cause injury.
• Do not use magnet for lifting or rigging applications — it is not certified lifting gear.
• Do not leave metal objects such as needles, knives or tools near magnets — they will be attracted unexpectedly and can cause injuries.
• Do not machine cut or drill magnets — drilling dust and shavings could ignite.
• Do not remove or damage the coatings — this will cause oxidation and demagnetisation.

Safety Information — Neodymium Magnets

IMPORTANT — READ BEFORE USE. Neodymium magnets are extremely strong. Improper handling can cause injury, equipment damage, or serious hazards.

Critical Warnings

• Handle with care: Can snap together violently, causing crushing injuries
• Not a toy: Keep away from children/pets. Choking and internal injury hazard if swallowed
• Field hazards: Affects pacemakers, medical implants, credit cards, electronics
• Required PPE: Protective gloves for larger magnets; safety glasses when magnets may collide

Handling, Storage & Environment

• Slide magnets together, never let them snap
• Use non-magnetic spacers for separation
• Store in cool, dry place with protective packaging
• Max temp ~80°C, avoid heat/flame
• Rinse after saltwater use, dry thoroughly
• Can corrode if coating damaged

Diving-Specific Safety

• Use safety lanyards to prevent loss
• Test attachment on surface first
• Beware strong pull near metal structures
• Keep away from dive computers/compasses
• Plan exit strategy before attaching

Health & Safety Precautions

• Medical Devices: Keep away from pacemakers, ICDs, insulin pumps. Consult doctor if you have implants.
• Allergies: Coatings often contain nickel. Avoid prolonged contact if sensitive.
• Children & Pets: Keep away at all times. Choking hazard. Swallowed magnets cause life-threatening injury.

Electronic Interference

Strong magnetic fields can damage: dive computers, cameras, smartphones, credit cards, magnetic ID/media, and data storage devices. Maintain safe distance during use and storage.

Machining & Dust Hazards

• Do NOT cut, drill, or grind without industrial equipment
• Magnet dust is highly flammable
• Never drop — can cause internal cracking
