Which of the following statements are true for magnetic field lines? Check all that apply.

A.) Magnetic field lines are close together in regions of space where the magnitude of the magnetic field is weak, and they are farther apart in regions where it is strong.

B.) Unlike electric field lines, magnetic field lines are continuous.

C.) Magnetic field lines point in the direction of the magnetic force acting on a charge.

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

E.) Magnetic fields can never intersect.

Expert Solution

B , D and E statements are true.

B.) Unlike electric field lines, magnetic field lines are continuous.

Electric field lines start at +ve charge and end at -ve charge. If there is no nearby -ve charge , electric the field line goes to infinity.

Since magnetic monopole cannot exist , the magnetic field lines start at north pole of a magnet ,end at south pole of the magnet, and are continuous.

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

For a magnetic field line , the direction of magnetic field vector at a point on the field line is tangential to field line.

E.) Magnetic fields can never intersect.

If two magnetic field lines intersect , at the point of intersection the magnetic field will have two directions, which is not possible, so they never intersect.

Below statements are false:

A.) Magnetic field lines are close together in regions of space where the magnitude of the magnetic field is weak, and they are farther apart in regions where it is strong.

The magnetic field lines are close together where the strength of magnet field is strong. and the lines are farther apart in regions where it is weak. The higher the density of field lines the stronger the field.

C.) Magnetic field lines point in the direction of the magnetic force acting on a charge.

Magnetic field lines give the direction of

Magnetic force is

So magnetic field direction cannot be the direction of magnetic force.
