Two long, straight wires, each carrying a current of 5A, are placed along the x and y axes respectively. The currents point along the positive directions of the axes. Find the magnetic fields at the points (a) (1m, 1m), (b) (-1m, 1m), (c) (-1m, -1m) and (d) (1m, -1m).

Explanation

To find the magnetic fields at the specified points due to two long, straight wires carrying currents of 5 A along the x and y axes, we will use the formula for the magnetic field created by a long straight wire:

\[ B = \frac{\mu_0 I}{2 \pi d} \]

where:
- \( B \) is the magnetic field,
