The correct answer is: If magnetic field lines are parallel and equidistant, they represent zero field strength.
- Magnetic field lines form closed loops and do not intersect.
- At any point, the magnetic field direction is tangent to the magnetic field line.
- If the magnetic field lines are parallel and equidistant, the magnetic field represents a uniform magnetic field rather than a zero field strength.
