A conductor $AB$ of length $l$ carrying a current $i$ is placed perpendicular to a long straight conductor $XY$ carrying a current $I$ as shown. The force on $AB$ will be

Options:

Answer:

Solution:

$d F = i d x B$

$d F = i d x \frac{μ_{0} I}{2 π x}$

$F_{A B} = \int_{\frac{l}{2}}^{\frac{3 l}{2}} \frac{μ_{0} i I d x}{2 π x}$

$F_{A B} = \frac{μ_{0} I i}{2 π} \ln 3$
