Moderate# Magnetic Field Above the Center of a Circle of Current

EANDM-HADYS0

Figure 1 depicts a field point a distance $h = 1.86 \text{ cm}$ above the center of a circle of current of radius $R = 1.53 \text{ cm}$. The current running through the circular wire is $I = 3.24 \text{ A}$.

What is the magnitude of the magnetic field at the field point $P$?
