Question

1a) A long hairpin is formed by bending a very long wire, as shown. If the wire caries a current of 16 A, what is the magnitude and direction of the magnetic field at the point a? Take R = 5 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.
1b)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.

The image depicts an electrical circuit diagram featuring a closed loop with key components and annotations:

- Two parallel horizontal lines represent the path of the current, indicating the direction with arrows and labeled as "i."
- There is a resistor in the loop, represented by the symbol "R," located near point "a."
- Points "a" and "b" are marked with red dots, indicating specific locations in the circuit.
- The current enters the circuit, flows through point "a," passing through the resistor (R), and continues towards point "b" before completing the loop.
- The path of the current is shown with solid lines, transitioning to dashed lines outside the circuit.

This diagram is likely used to illustrate concepts related to current flow, resistance, and essential points in an electric circuit.
