A piece of wire is bent to form a circle with radius r. It has a steady current I flowing through it in a counterclockwise direction as seen from the top (looking in the negative z direction).

Magnetic Field at the Center of a Wire Loop Part A A piece of wire is bent to form a circle with radius r. It has a steady current I flowing through it in a counterclockwise direction as seen from the top (looking in the negative z direction). (Figure 1) What is B, (0), the z component of B at the center (i.e., x = y = z = 0) of the loop? Express your answer in terms of I, r, and constants like Ho and T. Hints ?
