A square loop, carrying a steady current $I$ , is placed in horizontal plane near a long straight conductor carrying a steady current $I_{1}$ at a distance of $d$ from the conductor as shown in figure. The loop will experience

Options:

Answer:

Solution:

$F_{2} = - F_{4} F_{1} = \frac{μ _{0} I _{1} I l}{2 π d l} F_{2} = \frac{μ _{0} I _{1} I}{2 π ( d + l )} F_{1} > F_{3} F_{net} = F_{1} - F_{3}$ So, wire attract loop.
