Two straight infinitely long and thin parallel wires are spaced 0.1m apart and carry a current of 10A each. Find the magnetic field at a point distance 0.1m from both wires in the two cases when the currents are in the (a) same and (b) opposite directions.

Explanation

To solve the problem of finding the magnetic field at a point equidistant from two parallel wires carrying currents in both the same and opposite directions, we will follow these steps:

### Given:
- Distance between the wires, \( d = 0.1 \, \text{m} \)
- Current in each wire, \( I = 10 \, \text{A} \)
- Distance from each wire to the point of interest, \( r = 0.1 \, \text{m} \)

### Step 1: Calculate the magnetic field due to one wire
