What is the Difference Between Magnetic Field and Magnetic Flux?
🆚 Go to Comparative Table 🆚The main difference between magnetic field and magnetic flux lies in their definitions and how they are measured:
- Magnetic Field: This is a region in space where a magnetic effect due to the field is observed. It is the result of a moving charged particle and can produce a magnetic force. The magnetic field is expressed in units of Tesla (T) and is denoted by the letter H. It can be depicted with field lines, showing the direction of the force experienced by moving charges.
- Magnetic Flux: This is a measure of the magnitude of a magnetic field passing through a given area. It is defined as the total number of magnetic lines of force produced by a magnet and is measured in Webers (Wb). The magnetic flux can be calculated using the magnetic field density and the area through which the magnetic field passes, represented by the formula: Φ = B•A, where B is the magnetic field density and A is the area.
In summary:
- The magnetic field is a region in space where a magnetic force is observed, with units of Tesla.
- Magnetic flux is a measure of the magnetic field's magnitude passing through a given area, with units of Webers.

Comparative Table: Magnetic Field vs Magnetic Flux
Here is a table highlighting the differences between magnetic field and magnetic flux:
Property | Magnetic Field | Magnetic Flux |
---|---|---|
Definition | A magnetic field is a region in space where a magnetic force is exerted on objects. | Magnetic flux is a measure of the magnitude of a magnetic field passing through a given area. |
Symbol | H or B (dependencies on context) | B or Φ (dependencies on context) |
Unit of Measurement | Amps per meter (A/m) for magnetic field strength H | Teslas (or microteslas or gauss) for magnetic flux density B |
Directionality | Yes, magnetic field lines have direction. | No, a scalar quantity. |
Faraday's Law | Not directly related. | Directly related; states that an electromotive force is induced by a change in magnetic flux. |
In summary, a magnetic field is a region in space where magnetic force is exerted, while magnetic flux measures the magnitude of a magnetic field passing through a given area. Magnetic field has directionality, while magnetic flux is a scalar quantity. Faraday's Law is directly related to magnetic flux, stating that an electromotive force is induced by a change in magnetic flux.
