Question

Which of the following situations is/are possible?

(a) Magnetic field lines can be parallel to each other.

(b) Magnetic field lines can be concentric circles.

(c) Magnetic field lines can intersect each other.

• A. Only (b)
• B. Both (a) and (b)
• C. Both (a) and (c)
• D. Only (a)

Answer 1

Answer:

B. Both (a) and (b)

Magnetic field lines can be parallel in uniform fields and concentric around circular loops, but they do not intersect. Magnetic field lines generally originate from the North Pole of the magnet and end at the South Pole but inside the magnet, magnetic field lines are directed from the South Pole to the North Pole. Thus, we can say that magnetic field lines form a closed curve. They can never intersect with each other.
