Question
The accompanying figure shows two long, straight, horizontal wires that are parallel and a distance \(2a\) apart. Both wires carry current \(I\) in the same direction. Give your answer in terms of given variables (\(I\) and \(a\)) and physical and numerical constants (\(\mu_0\) and \(\pi\)).

**Diagram Explanation:**

- There are two parallel wires, each carrying a current \(I\) in the same direction, represented by arrows facing right.
- The distance between the two wires is \(2a\).
- There are two points of interest: \(P_1\) and \(P_2\).
  - \(P_1\) is located halfway between the wires at a distance \(a\) from each.
  - \(P_2\) is located below the second wire at a distance \(2a\).

**Questions:**

a. What is the magnetic field at \(P_1\)?

- **Answer Input:** The magnetic field at \(P_1\) is \(\_\_\_\_\_\_\_\).
  - **Format Hint:** Spell out Greek letters and use underscore ("_") for subscripts. For example, to type in \(\mu_0\), type in "mu_0".

b. What is the magnetic field at \(P_2\)?

- **Answer Input:** The magnetic field at \(P_2\) has magnitude \(\_\_\_\_\_\_\_\) and points \(\_\_\_\_\_\_\_\).
  - **Format Hint:** Spell out Greek letters and use underscore ("_") for subscripts. For example, to type in \(\mu_0\), type in "mu_0".
