Deep sea fishing suction cup round ring salvage magnet D25mm nickel-plated neodymium axial magnetising N35 grade working temperature 80°C for retrieving tools and metal objects underwater
D25mm round ring salvage magnet with nickel plating for deep sea fishing and underwater retrieval

This D25mm round ring salvage magnet provides practical metal retrieval capabilities for fishing applications where tools, lures, or equipment may be dropped into water. Constructed from neodymium iron boron with N35 material designation, it offers focused magnetic pull through its axial magnetising direction. The nickel-plated surface resists corrosion from prolonged water exposure, while the 80°C working temperature rating ensures performance across different environmental conditions. Measuring exactly 25mm in diameter, this compact magnet delivers substantial retrieval force for its size through its 1.22T remanence and 310KJ/m³ maximum magnetic energy product.
Features and Construction

The salvage magnet's construction centres on practical performance characteristics measured against standard material specifications. Each measurement contributes to its retrieval capabilities in underwater environments where visual locating may be difficult.
Material and Build
Neodymium iron boron forms the core material with N35 grade designation and 7.44g/cm³ density. Nickel plating provides surface protection against corrosion from freshwater and saltwater exposure. The magnet exhibits 1.22T remanence (magnetic induction remaining after magnetisation) and 868KA/m coercivity (resistance to demagnetisation). With 955KA/m intrinsic coercivity and 310KJ/m³ maximum magnetic energy product, it maintains strong retrieval force relative to its compact D25mm size.
Size and Practical Fit
The 25mm diameter circular design creates a focused retrieval area through its centre opening. Axial magnetising direction channels magnetic force perpendicular to the ring face rather than radially outward. This configuration concentrates pull through the ring's centre where retrieved items typically make contact. The compact dimensions allow attachment to various fishing lines or retrieval cords without adding excessive bulk or weight to setup configurations.
Uses and Placement

Primary applications centre on metal object recovery in aquatic environments where visual searching proves difficult. The magnet's specifications support both recreational and practical retrieval scenarios across different water types and conditions.
Event or Professional Use
For professional fishing operations, the magnet can retrieve dropped tools, equipment components, or metal fittings from boat decks or work areas. The 80°C working temperature accommodates use in various climates and storage conditions without performance degradation. Commercial fishing applications might include recovering metal components from nets or retrieving items accidentally dropped overboard during operations.
Everyday Home Use
Recreational anglers can use the magnet to recover lost lures, hooks, or fishing tools from lakes, rivers, or coastal waters. The nickel plating resists corrosion from periodic freshwater exposure during typical fishing trips. Hobbyists searching submerged areas for interesting metal objects benefit from the focused axial magnetising that concentrates force through the ring's centre opening.
Benefits and Buying Value

The magnet's value derives from its material specifications and practical design features that support repeated underwater use without performance degradation under normal conditions.
Reuse and Low Maintenance
Nickel plating reduces corrosion maintenance compared to uncoated magnets in aquatic environments. The 310°C Curie temperature provides thermal stability margin above the 80°C working rating, protecting against accidental exposure to heat sources. With proper care to avoid exceeding temperature limits, the magnet maintains its retrieval capabilities through multiple uses without requiring special conditioning or treatment between applications.
Why Choose This Product
The D25mm salvage magnet offers measurable specifications rather than general claims, with documented N35 grade material, axial magnetising direction, and specific temperature ratings. Its compact 25mm diameter provides substantial retrieval force through 1.22T remanence and 310KJ/m³ maximum energy product relative to size. The nickel plating specifically addresses corrosion concerns for water applications where other finishes might deteriorate more quickly.
