Question
Magnetic lines of force always exist in
- Straight line
- Closed curves
- Parabolic
- Hyperbolic
Hint:
Magnetic lines of force always exist in closed curves.
The correct answer is: Closed curves
- Due to the absence of magnetic monopoles in nature, magnetic lines form continuous closed loops.
- It is common to see magnetic poles, North and South, coupled together so that field lines coming from one pole terminate at the other, making a closed loop.
