Demagnetization is the process of reducing or eliminating the magnetic field of a material. This can occur through various methods, such as heating, hammering, or exposing the material to a strong external magnetic field in the opposite direction.
Magnetic fields are regions of space where magnetic materials or moving electric charges experience a force. They are created by the movement of electric charges, such as the flow of current in a wire or the alignment of magnetic dipoles in a material.
Magnetic fields can be visualized using magnetic field lines, which show the direction and strength of the magnetic field at different points in space. These field lines form closed loops around a magnetic material or a current-carrying wire.
Magnetic fields play a crucial role in many everyday devices, such as electric motors, generators, and MRI machines. They also have important applications in industries such as electronics, telecommunications, and transportation.

Demagnetization
- Definition: The process of reducing or eliminating the magnetic field strength of a material.
- Causes:
- Magnetic fields from external sources (e.g., magnets, current-carrying conductors)
- Mechanical stress or vibration
- Heat treatment
- Gradual loss of magnetization over time (magnetic creep)
Magnetic Fields
- Definitions:
- Magnetic field: An invisible region around a magnet or current-carrying conductor where magnetic forces can be detected.
- Magnetic flux density: The amount of magnetic field strength present at a point in space.
- Magnetic field intensity: The force experienced by a moving charge in a magnetic field.
- Properties:
- Directly proportional to electric current: Stronger currents create stronger magnetic fields.
- Inversely proportional to distance: Magnetic field strength decreases with distance from the source.
- Circular pattern: Lines of magnetic force form loops or circles around a current-carrying conductor or magnet.
- Opposite poles: Magnetic fields have two opposite ends called poles (north and south) with like poles repelling and unlike poles attracting.
- Applications:
- Motors and generators
- MRI machines
- Magnetic storage devices (e.g., hard drives)
- Magnetic resonance therapy
