FREE Expert Solution

The magnetic field for each semi-circle is given by:

B=μ0I4r

Let's take the magnetic field on the inner semi-circle to be B1 and that on the outer semicircle to be B2.

What is the strength of the magnetic field at point P in the figure?The figure shows a current loop of a semicircular arc shape. The inner radius is r subscript 1 baseline. The outer radius is r subscript 2 baseline. The semicircular segments are connected by horizontal segments. The current I flows counterclockwise through the loop. Point P is marked at the center of the curvatures, below the loop. Assume that I = 5.2 A , r1 = 1.1 cm , and r2 = 2.2 cm .

What is the direction of the magnetic field at point P in the figure?
