1. Magnets. Magnetic poles.

In this video you can actually see the magnetic field lines produced by a magnet.

2. The magnetic field.

In this interesting video you can see the magnetic field lines produced by several arrangements of currents (coils).

Look at the lines of the last example, the solenoid. Compare them with the lines produced by the magnet. Both have N and S poles. In the solenoid you can see how are the lines inside the magnet!.

3. SOHO (Solar and Heliospheric Observatory).
