Question

With reference to the properties of the magnetic lines of force, consider the following statements:
1. Magnetic lines of force outside the magnet, are from the north pole to the south pole.
2. If magnetic lines of force are parallel and equidistant, the magnetic field is uniform.
Select the correct answer using the code given below:

Which of the following options is correct?

1. 2 only
2. 1 only
3. Both 1 and 2
4. Neither 1 nor 2

Answer 1

Correct Answer - Option 3 : Both 1 and 2

The correct answer is Both 1 and 2.

• The magnetic lines of force are closed curves. 

• Outside the magnet, they are from north pole to south pole.
• Inside the magnet they are from south to north pole.
• Two lines of force never intersect one another.
• If magnetic lines of force are parallel and equidistant, the magnetic field is uniform.
• If magnetic lines of force are crowded, then the magnetic field is strong. 
• The strength of the magnetic lines is the uniform throughout and is proportional to how close are the lines.
