2.1.2. Magnets Magnetic field
Bodies of ferromagnetic materials (e.g. iron, nickel, cobalt, etc.) have a magnetic field in their vicinity.
Direction of field lines
As indicated in Figure 2 the field lines emerge from the north pole and enter the south pole. Inside the magnet the field lines run from the south to the north pole.
Magnetic poles always arise pairwise.
Magnetic force action law - magnets interact with each other.
