Keys to magnetic field testing and permeability

Magnetic field testing measures the degree by which the presence of a magnetic field will effect a material. this property of being attracted to a magnetic field is known as paramagnetism. if your products are being used in an environment, such as those around an mri, it will be important for your customer to know if your product is paramagnetic.

Principles of magnetism

The magnetic field configuration of two permanent magnets is illustrated in figure 5.magnet a has a long air return path for the magnetism from the one north pole end to the south pole end, so the magnetism flux density is weak, while magnet b has a short air return path, so the magnetism flux density is intense.
