Study Unveils New Friction Insights from Magnetic Behavior

3/23/2026

Summary

Story summary

Researchers at the University of Konstanz discovered non-contact sliding friction from collective magnetic behavior, challenging Amontons' law.
In experiments, a two-dimensional array of magnetic elements showed that friction peaks when magnetic ordering is frustrated.
Friction is lowest when layers are very close or far apart but peaks at intermediate distances due to competing magnetic preferences.
The findings could enable frictional metamaterials and adaptive damping systems.
