Based on results of two quite different experiments, we report microslip‐induced degraded performance of a braided superconductor. Microslips, or more formally, microscopic slips, are inherent in all sliding events and are quite different from the well‐known stick slips that occur, on a macroscopic scale, for ’’unstable’’ sliding pairs. Microslips occur universally in all material pairs. Their effects are, in general, innocuous except in low‐temperature situations such as those found in superconducting magnet windings. Because materials have extremely low‐heat capacities at 4.2 K, the miniscule amount of energy released by a microslip can precipitate a quench in the superconducting magnets.
