Four wires each of length 2 m are bent into four loops P, Q, R and S and then suspendedi nto uniform magnetic field. Same current is passed in each loop. Which statement is correct?
Correct answer: D. Loop S (Circle)
- A. Loop P (Square)
- B. Loop Q (Horizontal Rectangle)
- C. Loop R (Vertical Rectangle)
- D. Loop S (Circle)
Explanation
Understanding the shapes of the loops helps determine their relative torques in a magnetic field. The area of a circle is maximized compared to shapes of equal perimeter, which may result in loop S having a relatively higher torque compared to the other loops, assuming all loops have the same current and the area encloses the same amount of space.Conclusion:Considering the shapes and their respective orientations in the magnetic field, the circle (loop S) might have the highest torque compared to loops P, Q, and R. Revised Answer (d) Couple on loop S (circle) will be the highest

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
