Which of the following statements are true for magnetic field lines? Check all that apply. a. At every point in space, the magnetic field vector at that point is tangent to the magnetic field line through that point. b. Magnetic field lines are close together in regions of space where the magnitude of the magnetic field is weak, and they are father apart in regions where it is strong. c. Unlike electric field lines, magnetic field lines are continuous. d. Magnetic field lines point in the direction of the magnetic force acting on a charge. e. Magnetic field lines can never intersect.

a. True

c. True

e. True

Explanation:

a. At every point in space, the magnetic field vector at that point is tangent to the magnetic field line through that point. True

Since we know that the field direction is always tangent to the field line at any point in space.

c. Unlike electric field lines, magnetic field lines are continuous. True

Since magnetic field lines have continuous closed loops as they start from the north pole then to south pole and then return to the north pole forming a closed loop.

e. Magnetic field lines can never intersect. True

Since we know that the field is unique at any point in space, therefore, it is not possible that the field lines will intersect.
