• Magnet fixation: Epoxy resin (permanent bonding)

Product Construction & Performance

This magnetic holder is precision-engineered to maximize pulling force and durability:

• Precisely calculated magnetic gap and housing thickness optimize magnetic performance

• The neodymium magnet is bonded with epoxy resin, protecting it against:

  • detachment,

  • shocks and vibrations,

  • water and debris ingress

• Robust steel housing enhances both magnetic efficiency and mechanical protection

Why Does the Housing Thickness Matter?

In this type of magnetic holder:

• one magnetic pole acts directly on the attracted object,

• the opposite pole transfers magnetic energy into the steel housing.

As a result, the housing itself becomes magnetized, generating an additional magnetic field.
The material, wall thickness, and magnetic gap are therefore critical factors for:

• achieving maximum pulling force,

• protecting the neodymium magnet,

• ensuring long-term reliability during magnetic fishing.

Important Notice – Pulling Force Measurement

* The stated maximum pulling force is measured under ideal laboratory conditions:

• using a calibrated tensile testing machine,

• with the magnet attached to a thick, flat, clean steel surface,

• force applied vertically.

In real-world conditions, the actual pulling force will be lower when:

• the metal object is thin or uneven,

• the surface is rusty, painted, or contaminated.

Depending on surface conditions, pulling force may be reduced by up to 70%.
