According to Biot-Savart’s law, the magnetic field at a point due to the incremental element of length dl carrying a current is given by
Where B is a magnetic field in Tesla
I, is the current in the wire in Ampere
r is the radius of the wire in meter
From the above expression, it is clear that the magnetic field at a point due to the incremental element of length dl carrying a current is directly proportional to the current carried by the element.
Magnetic field intensity for Various Current Distribution
For line current
Surface current
Volume current
In all lines, surface and volume.
The magnetic intensity is inversely proportional to the Square of the distance between them.
