What is Hysteresis loop ? Explain with the help of terms related to it.

Explanation

### Step-by-Step Solution:

1. **Definition of Hysteresis Loop**:
The hysteresis loop is a graphical representation of the relationship between the magnetic field strength (H) and the magnetization (I or B) of a magnetic material when it is subjected to a cyclic change in the magnetic field. It illustrates how the magnetization of the material lags behind the applied magnetic field.

2. **Magnetic Field Application**:
Begin with a magnetic material placed in a variable magnetic field. As the magnetic field strength (H) is increased from 0 to a maximum value (point A), the magnetization (I or B) of the material also increases from 0 to a maximum value (point A).
