Question

Choose the correct statement/statements from the following options regarding the magnetic field lines of an electromagnet.

• A. The magnetic field lines do not form closed lines.
• B. The magnetic field lines are closed lines.
• C. If magnetic field lines are parallel and equidistant, they represent zero field strength.
• D. Magnetic field lines do not intersect each other.

Answer 1

Answer: (B), (D)

The correct options are
B

The magnetic field lines are closed lines.

D

Magnetic field lines do not intersect each other.

If the magnetic field lines are parallel and equidistant, they represent a uniform magnetic field and not a zero field strength. Also, magnetic field lines form a closed loop as shown in the figure below. Therefore options (A) and (C) are the incorrect statements and the two options are correct.
