Biot Savart Law

For an infinitely long wire bent into a semi-circular shape, we can use the Biot-Savart law to find the magnetic field at the center of the semi-circular loop.
The formula for the magnetic induction along the axis of a semi-circular loop of current is given by: Where: - is the permeability of free space, - is the current, - is the radius of the semi-circular loop. Given that the radius is 1 m and the magnetic field along the axis is directed along the line passing through the center of the semi-circle, the magnitude of the magnetic induction is .
Thus, the magnetic induction is .
