| Magnetic field due to current in a circular arc of wire. |
Consider an arc of a circle having arc length L as shown in the figure. Let I be the current flowing through the arc. Let r be the radius of the arc. Let point O be the point where magnetic field is to be determined. Consider a small current element dl, thus the magnetic field due to small element is given by,
