Hysteresis Loss:

Hysteresis loss is a type of energy loss that occurs in magnetic materials due to the lagging of the magnetization of the material behind the changes in the magnetizing field. This phenomenon is known as hysteresis and the associated energy loss is known as hysteresis loss.

Step by Step Explanation:

1. When a magnetic field is applied to a magnetic material, it becomes magnetized. The magnetization of the material lags behind the changes in the magnetizing field. This is known as hysteresis.

2. The hysteresis loop, which is a plot of the magnetizing field (H) against the magnetization of the material (B), shows this lag. The area inside the hysteresis loop represents the energy loss per unit volume per cycle, which is the hysteresis loss.

3. The hysteresis loss is given by the equation: Hysteresis loss = ηB^1.6, where η is the hysteresis coefficient and B is the maximum flux density.

4. The hysteresis loss can be reduced by using materials with a narrow hysteresis loop, such as silicon steel.

Eddy Current Loss:

Eddy current loss is a type of energy loss that occurs in magnetic materials due to the formation of circulating currents, known as eddy currents, within the material when it is subjected to a changing magnetic field.

Step by Step Explanation:

1. When a magnetic material is subjected to a changing magnetic field, circulating currents, known as eddy currents, are induced within the material. These currents are due to Faraday's law of electromagnetic induction.

2. The eddy currents flow in loops within the plane of the material, and they generate heat due to the resistance of the material. This heat represents an energy loss, which is the eddy current loss.

3. The eddy current loss is given by the equation: Eddy current loss = kE^2f^2B^2t^2, where k is a constant, E is the thickness of the material, f is the frequency of the magnetic field, B is the maximum flux density, and t is the thickness of the material.

4. The eddy current loss can be reduced by using materials with high resistivity, such as ferrite, or by laminating the material, which breaks up the path of the eddy currents.
