Magnetic field lines are imaginary lines used to represent the direction and strength of a magnetic field. They emanate from the north pole of a magnet and curve around to enter the south pole.
5 Must Know Facts For Your Next Test
Magnetic field lines never intersect each other.
The density of magnetic field lines indicates the strength of the magnetic field; closer lines mean a stronger field.
Inside a magnet, magnetic field lines run from south to north, completing a closed loop.
The direction of magnetic field lines at any point gives the direction of the magnetic force on a north pole placed at that point.
Magnetic flux through a surface is proportional to the number of magnetic field lines passing through it.
Waves composed of oscillating electric and magnetic fields, which propagate through space carrying energy.
$\mathbf{B}$-field: \(\mathbf{B}\)-field, or Magnetic Field, is represented by vector $\mathbf{B}$ and describes the influence exerted by magnets or moving charges.
