Above the Curie point, ferromagnetic substances have this property, which also applies to liquid oxygen and other molecules with unpaired electrons.
Langevin's law says that the magnetic force on a membrane with this property is always attractive, and the deflection of a membrane with this property is proportional to the gradient of the square of an external magnetic field. Above the Curie point, ferromagnetic substances have this property, which also applies to liquid oxygen and other molecules with unpaired electrons. For 10 points, name this type of magnetism in which a material becomes magnetic in the presence of an external magnetic field, which is stronger than diamagnetism.
Langevin's law says that the magnetic force on a membrane with this property is always attractive, and the deflection of a membrane with this property is proportional to the gradient of the square of an external magnetic field.
