The magnetic lines of force are directed in a manner that they:
Correct answer: C. Originate at north pole and terminate at south pole
- A. Originate at south pole and terminate at north pole
- B. Pass through the magnet
- C. Originate at north pole and terminate at south pole
- D. Go away from both the poles
Explanation
The correct answer is Option C: The magnetic lines of force originate at the north pole and terminate at the south pole. This is because magnetic field lines emerge from the north pole and enter the south pole, completing a loop.Option A is incorrect because it reverses the direction of the magnetic lines of force, which do not originate at the south pole.Option B is incorrect in context because, while magnetic lines do pass through the magnet as continuous loops, it does not address their directional origin and termination.Option D is incorrect because magnetic lines of force do not move away from both poles; they form loops, ensuring the magnetic field is present outside the magnet.

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.
