Discrepancy between claimed field flux density of some commercially available magnets and actual gaussmeter
1Division of Orthodontics, School of Dental and Oral Surgery, Columbia University, New York, NY, USA.
Context:
Magnets are widely used by the public in medical applications.
Objectives:
To determine whether the field flux density, a measurement of magnetic dosage, provided by over-the-counter magnet manufacturers is accurate.
Design:
Five magnets were tested for field flux density, and measurements were compared with information provided by manufacturers.
Results:
Magnets studied showed actual field flux density measurements that were significantly lower than the values claimed by suppliers.
Conclusions:
Over-the-counter magnet suppliers are not providing reliable information; therefore, clinical replication of published reports is difficult.

Magnetic Susceptibility and Permeability
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...
