Advantages of Hysteresis Loop
- The loss of hysteresis is shown by a decreased area of the hysteresis loop.
- The relevance of retentivity and coercivity is provided by the hysteresis loop to a material. As a result, the heart of machines makes it easier to choose the correct material for making a permanent magnet.
- The B-H graph may be used to determine residual magnetism, making a material selection for electromagnets straightforward.
Hysteresis Loop
Hysteresis Loop– In a system with a magnetic field, hysteresis occurs. Ferromagnetic materials have a common characteristic called hysteresis. The hysteresis effect is a phenomenon that occurs when the magnetization of ferromagnetic materials lags behind the magnetic field. The word hysteresis means “lagging.” Magnetic flux density (B) lags after magnetic field strength, resulting in hysteresis (H).
Hysteresis is a property of all ferromagnetic materials. Let’s look at an example where a ferromagnetic material is placed within a current-carrying coil to better grasp the notion. The material becomes magnetized as a result of the magnetic field present. Hysteresis is known as the process of demagnetizing a material by reversing the direction of the current.
