Moderate# Magnetic Field in the Center of an Arc of Current

EANDM-MH2YOD

Figure 1 depicts a current traveling through a $60^{\circ}$ arc of current.

The radius of the arc is $r = 0.34 \text{ mm}$ and the current through the arc is $I = 2.6 \text{ A}$.

What is the magnitude of the magnetic field generated by the arc of current at the field point $P$, located at the center of the arc?
