Magnetic field lines can be entirely confined within the core of a toroid, but not within a straight solenoid. Why?

Magnetic field lines can be entirely condined within the core of toroid , but not within a straight solenoid . Why?

(A): Magnetic field lines can be entirely confined within the core of a toroid. But not within a straight solenoid. (R) : The magnetic field inside the solenoid is uniform.

A: Magnetic field lines can be entirely confined within the corre of a toroid. R: Magnetic field lines cannot be entirely confined within the corer of a straight sotenoid.

Magnetic field lines inside a solenoid

Why can't two magnetic field lines cross each other? Draw the magnetic field lines (including field directions) of the magnetic field due to a long straight solenoid. What important property of this field is indicated by this field line pattern? Name any two factors on which the magnitude of the magnetic field due to this solenoid depends.

Which of the following statements are correct? (A) Electric monopoles do not exist whereas magnetic monopoles exist. (B) Magnetic field lines due to 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 paralle. (E) x=-1 is the condition for a perfect diamagnetic material, where x is its magnetic susceptiblity.
