Which of the following statements are correct?


Which of the following statements are correct?

(A) Electric monopoles do not exist whereas magnetic monopoles exist.

(B) Magnetic field lines due to a solenoid at its ends and outside cannot be completely straight and confined.

(C) Magnetic field lines are completely confined within a toroid.

(D) Magnetic field lines inside a bar magnet are not parallel.

(E) $\chi=-1$ is the condition for a perfect diamagnetic material, where $\chi$ is its magnetic susceptibility.

Choose the correct answer from the options given below :

  1. (C) and (E) only

  2. (B) and (D) only

  3. (A) and (B) only

  4. (B) and (C) only

Correct Option: 1


Statement (C) is correct because, the magneti field outside the toroid is zero and they forr closed loops inside the toroid itself.

Statement (E) is correct because we know the super conductors are materials inside which th net magnetic field is always zero and they a perfect diamagnetic.




For superconductors.
