What is magnetic hysteresis?
Magnetic hysteresis explanation- When a magnetic material like iron is magnetized by applying a magnetic field and then the field is removed or reversed, the material doesn’t immediately lose its magnetism - it remembers the magnetization for a while. This delay or memory effect is called magnetic hysteresis.
Hysteresis Loop is a graph of magnetization (B or M) vs magnetic field (H). The loop shows how the material responds to being magnetized and demagnetized.
