Question 17 of 57
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) is the condition for a perfect diamagnetic material, where is its magnetic susceptibility.
Choose the correct answer from the options given below :
Show answer and solution
Answer: (A) (C) and (E) only
Statement (C) is correct because, the magnetic field outside the toroid is zero and they form closed loops inside the toroid itself.
Statement (E) is correct because we know that super conductors are materials inside which the net magnetic field is always zero and they are perfect diamagnetic.
For superconductors.
