Thiết bị đo từ trường Laboratorio Elettrofisico PFMM Permeameter
he 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
