The force between two parallel current carrying conductors placed at an x distance apart and carrying the same current I, is:
1
\(\frac{{2\pi \times {{10}^{ - 7}}{I^2}}}{x}N/m\)
2
\(\frac{{2 \times {{10}^{ - 7}}{I^2}}}{{\pi x}}N/m\)
3
\(\frac{{2 \times {{10}^{ - 7}}{I^2}}}{x}N/m\)
4
\(\frac{{4\pi \times {{10}^{ - 7}}{I^2}}}{x}N/m\)
