Question

Pick the false statement on the magnetic field lines.

• A. They are imaginary lines
• B. They are two dimensional
• C. They are closed loops
• D. They never intersect with each other

Answer 1

The Correct Option is B

Correct answer: They are two dimensional 

Explanation:
Let’s analyze each statement about magnetic field lines: 

1. They are imaginary lines – True
Magnetic field lines are used to represent the direction and strength of magnetic fields; they are not physically real. 

2. They are two dimensional – False
Magnetic field lines exist in three dimensions. They form closed loops from the north to the south pole outside a magnet and continue through the magnet from south to north. 

3. They are closed loops – True
Unlike electric field lines, magnetic field lines always form closed continuous loops. 

4. They never intersect with each other – True
If two magnetic field lines were to intersect, it would imply two directions of the magnetic field at a single point, which is not possible. 

Hence, the false statement is: They are two dimensional.
