About SNJ 90

The SNJ-90 Hook Magnet is a high-strength neodymium (NdFeB) magnet assembled with a stainless-steel housing and integrated hook/eyebolt designed for heavy pulling force and versatile application. It belongs to the wider SNJ & LNJ series of hook magnets commonly used for magnet fishing, salvage, lifting, tool recovery and hanging applications.

Key Construction & Materials

Core Magnet: Made from neodymium (NdFeB), one of the strongest permanent magnetic materials available. This gives the SNJ-90 extremely high magnetic pull relative to its size.Hangzhou Yucheng Industrial Co., Ltd.
Shell & Casing: A steel casing surrounds the magnet, directing its magnetic flux downward toward the contact surface and protecting the brittle magnet core.SDM Magnetics Co., Ltd.
Coating: Typically nickel-plated for corrosion resistance and durability in outdoor or underwater environments.Hangzhou Yucheng Industrial Co., Ltd.
Hook / Eyebolt: Stainless-steel hook or eyebolt threaded into the body allows you to attach a rope, chain or lifting line. This component is usually either welded or screwed in securely.

How It Works

Magnet Force: The neodymium magnet produces a powerful magnetic field.
Steel Casing: Conducts and concentrates the magnetic flux to the base surface.
Hook / Eyebolt: You tie or attach a rope/line here.
Operation: Drop the magnet down to a target (usually for magnet fishing or object retrieval) and let it latch onto nearby ferrous metal items. This is ideal when searching waterways for lost tools, metal parts, or treasure.
