Measurement of magnetic fields List-Magnetik GmbH
The field lines of a magnetic field run from the north pole to the south pole of the magnet. In the case of a bar-shaped magnet e.g. the poles are mostly at the two ends. That is where the field is strongest. Depending on the shape of the magnet, the field lines run differently; in the horseshoe magnet they are parallel within the arch.

2022年9月12日The magnetic field lines of the infinite wire are circular and centered at the wire (Figure 12.3. 2 ), and they are identical in every plane perpendicular to the wire. Since the field decreases with distance from the wire, the spacing of the field lines must increase correspondingly with distance.
Electric and magnetic fields (article) Khan Academy
Magnetic fields Magnetic fields arise from permanent magnets and electric charges in motion. Magnets can occur naturally (such as the Earth’s magnetic field), or they can be made by magnetizing ferromagnetic materials. Magnetic fields ultimately are the result of the motion of charges.
Coercivity Wikipedia
Coercivity, also called the magnetic coercivity, coercive field or coercive force, is a measure of the ability of a ferromagnetic material to withstand an external magnetic field without becoming demagnetized.Coercivity is usually measured in oersted or ampere/meter units and is denoted H C.. An analogous property in electrical engineering and materials
