48mm Neodymium Fishing Magnet

This fishing magnet features a 48mm diameter magnetic body, providing a compact format for underwater searching and ferrous object retrieval.

The magnet can attract compatible magnetic materials such as:

• Iron
• Mild steel
• Magnetic steel
• Ferrous fasteners
• Steel tools
• Compatible steel components

The 48mm measurement describes the diameter of the magnetic body and should not be interpreted as a magnetic pull-force or retrieval-capacity rating.

Single M8 Threaded Eyelet

This fishing magnet is supplied with a single M8 threaded eyelet, providing an attachment point for a suitable rope or retrieval arrangement.

The eyelet can be used when:

• Lowering the magnet into water
• Searching vertically
• Retrieving submerged objects
• Recovering ferrous material from pits or drains
• Performing general magnetic recovery tasks

Before each use, check that the M8 threaded eyelet is correctly installed and securely engaged.

Threaded connections can loosen through repeated movement, vibration and changing load directions. The eyelet and associated retrieval equipment should therefore be inspected regularly.

Neodymium Iron Boron Rare Earth Magnet

This fishing magnet uses Neodymium Iron Boron (NdFeB), one of the strongest commercially available permanent magnetic materials.

The high magnetic performance of neodymium relative to its size makes NdFeB particularly useful for compact magnetic retrieval equipment.

Neodymium fishing magnets are designed to attract compatible ferromagnetic objects manufactured from materials such as:

• Iron
• Mild steel
• Magnetic steel
• Compatible ferrous alloys

The specific neodymium magnetic grade has not been supplied and should not be assumed.

What Can a Fishing Magnet Retrieve?

Depending on the material, size, shape, condition and accessibility of the target, potential finds may include:

• Nuts
• Bolts
• Screws
• Washers
• Steel tools
• Ferrous brackets
• Steel plates
• Iron components
• Magnetic hardware
• Chains
• Other compatible ferromagnetic objects

Not every metal is magnetic.

This fishing magnet will not effectively attract non-ferromagnetic materials such as:

• Aluminium
• Copper
• Brass
• Plastic
• Timber
• Glass

Many stainless steel grades may also provide weak or negligible magnetic attraction.

Magnet Fishing and Underwater Retrieval

The compact 48mm design can be useful for searching accessible waterways and other locations where ferrous objects may have been lost or submerged.

Potential locations include:

• Rivers
• Creeks
• Lakes
• Dams
• Ponds
• Drains
• Pits
• Wells
• Other permitted retrieval locations

Always check that access and magnet fishing are permitted at the intended location before beginning.

Magnetic Pull Force vs Real-World Retrieval Capacity

No specific pull force has been supplied for this 48mm fishing magnet and a value should not be inferred from its diameter.

Even when a fishing magnet has a stated laboratory pull-force figure, that value does not represent a guaranteed real-world retrieval capacity.

Magnetic pull testing is generally conducted under controlled conditions using suitable steel and favourable contact.

Real-world magnet fishing conditions can be significantly different.

Factors Affecting Retrieval Performance

Actual magnetic holding and retrieval performance can be affected by:

• Target steel thickness
• Steel composition
• Object size
• Object shape
• Available contact area
• Surface flatness
• Rust
• Paint
• Protective coatings
• Mud
• Sand
• Sediment
• Debris between the magnet and object
• Magnet orientation
• Pulling direction
• Mechanical leverage
• Water movement
• Object weight
• Objects being buried, trapped or obstructed

A heavy steel object with limited contact may be more difficult to retrieve than a smaller object that provides clean, flat contact with the magnet.

Direct Pull vs Sideways Loading

Magnetic holding performance varies depending on the direction of the applied load.

Direct pull occurs when force attempts to separate the target directly away from the magnetic working surface.

Shear or sideways loading occurs when the target is pulled parallel to the magnetic surface and is encouraged to slide.

During real-world retrieval, the magnet may experience:

• Sliding
• Shear force
• Mechanical leverage
• Uneven contact
• Changing load direction

These conditions can substantially reduce practical holding compared with an ideal pull-force test.

Rust, Mud and Sediment

Objects recovered during magnet fishing are frequently covered with:

• Rust
• Mud
• Silt
• Sand
• Algae
• Paint
• Corrosion
• Other debris

These materials can create physical separation between the magnet and target steel.

Even a relatively small gap can reduce magnetic attraction, so direct contact with clean ferromagnetic material generally provides better holding performance.

Permanent Magnetic Operation

This fishing magnet uses a permanent neodymium magnetic system.

It requires:

• No electricity
• No batteries
• No charging
• No external power source

Its magnetic field remains continuously active during normal use.

Selecting Rope and Retrieval Equipment

A suitable rope and connection system should be selected for the complete retrieval application.

Consider factors including:

• Expected loads
• Rope strength
• Knot strength
• Abrasion resistance
• Water exposure
• Retrieval distance
• Shock loading
• Environmental conditions

Inspect the rope, eyelet, knots and other connection components before each use.

The magnetic performance of the fishing magnet should not by itself be used to determine the required strength or rating of the retrieval equipment.

Magnet Fishing Safety

Magnet fishing combines strong permanent magnets, ropes, water and potentially sharp or hazardous recovered objects.

For safer use:

• Wear suitable protective gloves
• Wear appropriate footwear
• Keep fingers clear of magnetic pinch points
• Never wrap retrieval rope around your hands, arms or body
• Take care around deep or moving water
• Inspect the eyelet and rope before use
• Keep children away from strong neodymium magnets
• Use care when handling sharp, rusted or contaminated finds
• Do not put yourself in danger to recover a stuck magnet

Neodymium magnets can attract suddenly to nearby steel and may cause pinch or impact injuries.

Check Local Magnet Fishing Rules

Before magnet fishing, check applicable local laws, regulations, landowner requirements and access conditions.

Magnet fishing may be restricted or prohibited in some:

• Waterways
• Heritage locations
• Environmentally sensitive areas
• Private properties
• Bridges
• Docks
• Public infrastructure areas

Permission may be required before searching from private land or particular structures.

Recovered material should be removed and disposed of responsibly where appropriate.

Hazardous or Suspicious Finds

Underwater magnetic retrieval can occasionally uncover potentially hazardous objects.

If you recover or encounter an object that appears to be:

• Ammunition
• An explosive or suspected explosive
• A weapon
• A hazardous chemical container
• A suspicious object
• Potential evidence of criminal activity

Do not unnecessarily handle, clean, dismantle or transport the object. Keep other people away and contact the appropriate local authorities for guidance.

Please Note

This product is a Neodymium Fishing Magnet with a 48mm diameter magnetic body and a single M8 threaded eyelet, designed for magnet fishing, underwater searching and general ferrous object retrieval.

No specific pull force, Gauss rating, neodymium grade, coating or finish, overall height, magnetisation configuration, dimensional tolerance or maximum operating temperature has been supplied and these specifications should not be assumed.

Any magnetic pull-force figure should not be interpreted as a guaranteed real-world retrieval capacity or safe working load. Actual retrieval performance depends on target material, steel thickness, available contact area, rust, coatings, sediment, magnet orientation, pulling direction, water conditions and whether the object is obstructed or embedded.

Inspect the M8 threaded eyelet, rope, knots and other retrieval equipment before use and ensure all components are suitable for the intended application.

This fishing magnet is not certified lifting equipment and should not be used for overhead lifting or safety-critical load handling.

Check applicable local laws and obtain any required permission before magnet fishing. Handle strong neodymium magnets and recovered objects carefully, and keep magnets securely away from children, pacemakers and other medical implants, magnetic storage media and sensitive electronic equipment.
