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

Options:

Answer:

Solution:

$F_{1} > F_{2}$ as $F \propto \frac{1}{d}$ , and $F_{3}$ and $F_{4}$ are equal and opposite. Hence, the net attraction force will be towards the conductor. Heat gain $=$ heat lost
