The magnetic field is a measure of the strength of magnetism at a given location. It is a vector quantity and is represented by magnetic field lines, which show the direction and intensity of the field at that location.
Magnetic flux, on the other hand, is the product of the magnetic field and the surface through which it flows. It is represented by a scalar quantity and is measured in Weber (Wb).
The magnetic flux through a surface can be calculated by multiplying the value of the magnetic field by the surface and the angle between the field and the surface.
In short, the magnetic field is a measure of the strength of magnetism at a given location, while the magnetic flux is the product of the magnetic field and the surface through which it flows.
Difference Between Magnetic Field And Magnetic Flux
Magnetic field
The magnetic field is a measure of the strength of magnetism at a given location. It is represented by magnetic field lines, which show the direction and intensity of the field at that location.
The magnetic field can be produced by both natural bodies and artificial devices, such as magnets or coils of wire.
Formula Of Magnetic Field:
 |
Where,
- F is the Force
- q is the charge
- V is the velocity of the charge
- And B is the magnetic field acting on the charge particle.
The magnetic field can be measured using a device called a magnetometer. The unit of measurement for the magnetic field is the tesla (T), which is a measure of the strength of the magnetic field.
The magnetic field has important applications in many areas, such as electricity, electronics, medicine and engineering.
For example, it is used in the manufacture of magnets, in the generation and distribution of electricity, in the production of nuclear energy, in medicine to perform magnetic resonance imaging, and in aerospace engineering to protect astronauts from cosmic radiation.
Magnetic flux
Magnetic flux is the product of the magnetic field and the surface through which it flows. It is represented by a scalar quantity and is measured in Weber (Wb).
The magnetic flux through a surface can be calculated by multiplying the value of the magnetic field by the surface and the angle between the field and the surface.
Formula Of Magnetic Flux:
Where,
- B is the magnetic field.
- A is the unit area through which magnetic field pass.
Magnetic flux is an important quantity in physics and electrical engineering, as it relates to the magnetic energy stored in a magnetic field and the amount of electricity that flows through a coil or electrical circuit.
Magnetic flux is also related to the Faraday-Lenz law, which states that a change in magnetic flux through a closed surface produces an electric current on the surface.
This law is used in electrical engineering to design transformers and electric motors.
