Laboratorio Elettrofisico Permeameter for feebly magnetic materials: Model PFMM

PFMM Permeameter

PFMM Permeameter

The Permeameter for feebly magnetic materials (model PFMM) verifies that a non-magnetic material, such as austenitic stainless steel, is actually non-magnetic. The permeameter quantifies the magnetic weakness of the material by measuring its magnetization curve, relative permeability and susceptibility.

When a non-magnetic material is used in an application where interaction with magnetic fields must be very low, the control of its magnetization and permeability is fundamental.

Common application examples:

  • Turbo generators
  • NMR instrumentation
  • Ionic devices
  • Electron beam devices
  • Precision weights
