What is the Difference Between Magnetic Intensity and Intensity of Magnetisation?
🆚 Go to Comparative Table 🆚The key difference between magnetic intensity and intensity of magnetization lies in their definitions and the parameters they describe:
- Magnetic Intensity (H): This is a quantity used to describe the magnetic field. It represents the magnetic field strength at a particular place and is defined as the magnetic dipoles per unit of volume. The formula for magnetic intensity is H = (μ0/4π) (M/r^3).
- Intensity of Magnetization (I): This refers to the change in the magnetic moment of a magnet per unit volume. It is defined as the net magnetic moment acquired per unit volume of a specimen. The formula for the determination of intensity of magnetization is I = M/V, where I is the intensity of magnetization, M is the magnetic moment, and V is the volume.
In summary, magnetic intensity is a quantity used to describe the strength of a magnetic field, while the intensity of magnetization describes the change in the magnetic moment of a magnet per unit volume.
Comparative Table: Magnetic Intensity vs Intensity of Magnetisation
The main difference between magnetic intensity and intensity of magnetization lies in their definitions and applications. Here is a table comparing the two concepts:
Property | Magnetic Intensity | Intensity of Magnetization |
---|---|---|
Definition | Magnetic intensity defines the forces that the poles of a magnet experience in a magnetic field. | Intensity of magnetization describes the net magnetic moment acquired per unit volume of a specimen. |
Unit of Measurement | Not applicable (force) | Ampere per meter (A/m) |
Direction | Similar to the direction of the magnetic field. | Similar to the direction of the magnetic moment. |
Dependence | Independent of the nature of the material and temperature. | Dependent on the nature of the material and temperature. |
Formula | Not applicable (force) | M = mnetV, where M is the intensity of magnetization, V is the volume of the specimen, and mnet is the net magnetic moment. |
In summary, magnetic intensity is a force that describes the interaction between magnets and magnetic fields, while intensity of magnetization is a vector quantity that represents the net magnetic moment per unit volume of a specimen. The intensity of magnetization depends on the material's properties and temperature, whereas magnetic intensity is independent of these factors.
