Magnetic field lines are always nearly normal to the surface of a ferromagnet at every point.

The magnetic field lines

Magnetic field lines show the direction (at every point) along which a small magnetised needle aligns (at the point). Do the magnetic field lines also represent the lines of force on a moving charged particle at every point ?

Draw magnetic field lines due to a U-shaped magnet?

Magnetic field lines are discontinuous curves. Is this statement true.

Draw magnetic field lines, when a paramagnetic substance is placed in an external magnetic field.
