Question

A long hairpin is formed by bending a very long wire, as shown.

a) If the wire caries a current of 12 A, what is the magnitude and direction of the magnetic field at the point a? Take R = 6 mm. Take the sign of B to be positive if the direction is out of the paper and negative if B is into the paper. You need to enter the number with its sign and a space and the unit.

b)What is the magnitude and direction of the magnetic field at the midpoint b? The distance between a and b are much larger than R (each straight section is "infinite"). Take the sign of B to be positive if the direction is out of the paper and negative if B is into the paper.

**Problem 8c29p11:**

A long hairpin is formed by bending a very long wire, as shown. If the wire carries a current of 12 A, what is the magnitude and direction of the magnetic field at point a? Take R = 6 mm. Take the sign of B to be positive if the direction is out of the paper and negative if B is into the paper. You need to enter the number with its sign and a space and the unit.

**Diagram Explanation:**

The diagram depicts a wire bent into a hairpin shape with a current (i) of 12 A flowing through it. The wire curves at point R, forming two straight sections. There are two marked points, a and b, along the path.

- Point R is the midpoint of the bend.
- Point a is located on the arc of the bend.
- Point b is positioned along the path of the straight section of the wire.
