The number of magnetic field lines passing through a given area is known as Magnetic flux. It is denoted by the symbol, and its unit is \(weber\) ().
Field lines crossing in a particular area
Magnetic flux density:
Magnetic flux density is defined as the number of magnetic field lines crossing a unit area in a direction that is normal to the direction of the field lines. is the unit of measurement for magnetic flux density.
Properties of magnetic lines of force:
- Magnetic lines of force are continuous, closed curves that run through the length of a magnet's body.
- Magnetic lines of force run from the north pole to the south pole.
- Magnetic lines of force never cross one another.
- Magnetic lines of force will be highest at the poles and lowest at the equator.
- The magnetic field direction is determined by the tangent drawn at any point on the curved line.
