SUMMARY
The magnetic field strength of ferromagnetic materials, such as bar magnets, is determined by the strength of the external magnetic field used to create it and the material's magnetic susceptibility. A definitive formula for calculating the magnetic field strength, denoted as B(r), is not universally established. For practical measurement, utilizing a Hall effect meter is recommended to assess the magnetic field at specific points. Alternatively, heating the magnet above its Curie point can allow for the induction of a magnetic field.
