What is current law magnetic field?

Published in Electromagnetism 1 min read

The magnetic field due to a current is described by the Biot-Savart law, which dictates the magnitude and direction of the magnetic field generated by each segment of current. This law states that each segment of a current-carrying wire produces a magnetic field, similar to that of a long, straight wire. The total magnetic field from any shaped current is then the vector sum of all the individual fields created by each of these segments.

In essence, understanding the magnetic field due to a current involves two key concepts:

  • Individual Segment Fields: Each tiny piece of the current contributes a small magnetic field.

  • Vector Summation: The total magnetic field is found by adding up all these tiny magnetic field vectors.
