In magnetic fastening architecture, overall holding power is determined by flux vector alignment rather than mass alone. When developing linear fasteners, choosing between radial and axial magnetization determines closure reliability. magtech® engineers proprietary multipole geometries for textile integration.

1. The Limitations of Axial Extrusion

In standard axially magnetized extrusions, north and south poles are separated across the cord's opposite ends. In a meter-long line, this produces weak localized surface flux in the center and intense field leakage at the terminals, leading to erratic closure along the zipper path.

2. Radial Multipole Configuration

Genuine magtech® magnetic cords (such as our CXX-1601 and CLL-1101 lines) are radially magnetized through custom pulse fixtures. Continuous polarity bands traverse the profile perpendicularly. When paired as Line A and Line B, the magnetic circuit completes instantly along the entire length, eliminating dead zones.

3. Increasing Parallel Shear Resistance

Garment plackets undergo shear forces (parallel sliding) whenever the wearer twists or leans. Radial alignment concentrates magnetic field vectors across tight contact surfaces, delivering shear force up to 1.65 N/cm and holding closures firm under movement stress.
