How is magnetic field (B) developed in a magnetic material placed in a region of an applied magnetizing force (H)?

The development of a magnetic field (B) in a magnetic material subjected to an applied magnetizing force (H) occurs through the process of induction. In this context, induction refers to the phenomenon where a magnetic field is generated within the material as a response to the external magnetizing force. When the magnetic material is exposed to H, its internal structure, particularly the magnetic domains, becomes aligned in the direction of the applied force. This alignment results in the creation of a magnetic field within the material, leading to an increase in its magnetic flux density (B).

Induction is a fundamental concept in magnetism and is crucial for understanding how materials behave when subjected to external magnetic fields. The level of magnetization depends on factors like the material's permeability and the strength of the applied magnetizing force. Unlike conduction, which pertains to the flow of electrical charge, or heat transfer, which relates to thermal energy movement, induction specifically describes the changing state of magnetization in response to an external influence. Magnetic domain transfer is not a commonly used term in this context and does not accurately describe the induction process. Therefore, induction is the appropriate term for the phenomenon described in the question.
