Single correct option
Consider the following statements about magnetic field lines:
1. They form closed loops.
2. Two field lines can intersect each other.
Which of the statements given above is/are correct?
1. They form closed loops.
2. Two field lines can intersect each other.
Which of the statements given above is/are correct?
- A. 1 only
- B. 2 only
- C. Both 1 and 2
- D. Neither 1 nor 2
Show answer and solution
Answer: (A) 1 only
Magnetic field lines emerge from the north pole and return through the magnet to the south pole, so they form continuous closed loops. Two lines cannot cross because at the crossing point the field would have two directions, which is impossible. Hence only statement 1 is correct.
