The answer is D.
The shapes of the magnetic field lines of a bar magnet are closed. By convention, the direction of the field is taken out of the north pole and entering through the south pole of the magnet.
The term that describes the number of thoughs that pass a point in a given amount of time is FREQUENCY.
In wave theory, frequency refers to the number of wave that pass through a fixed point in a given amount of time. Frequency is usually measure in Hertz. The mathematical formula for finding frequency is:
F = Velocity of wave / wavelength of wave.
