The Magnet Playground.

Interactive calculators for pull force, field strength, holding force, and air-gap behavior. Built for engineers, not marketers.

What's inside

A quick orientation.

The Playground covers the calculations engineers reach for most often when scoping a magnet or an assembly.

F

Pull force

Force-to-steel for various magnet shapes, grades, and contact conditions.

B

Field strength

Gauss readings on the magnet surface and at a specified distance along the axis.

H

Holding force

Estimates for ferromagnetic holding applications across common geometries.

G

Air gap

Field behavior across an air gap — useful for sensors, actuators, and reed switches.

Calculator results are estimates based on idealized conditions. For tolerance-critical or temperature-dependent applications, bring the spec to our engineering team for a full FEA review.

Need more than an estimate?

For programs where the math has to land within a few percent, bring the application to engineering for full FEA modeling.
