Attractions and repulsive forces of a magnet
Tiny circular currents at the atomic level are responsible in a permanent magnet for exerting a magnetic force. It is so strong even with small magnets that you can clearly feel them.
-
Curie constant
By means of the Curie constant, the magnetic attraction of a substance as a function of the temperature can be determined.
-
Curie temperature
The temperature at which a ferromagnetic becomes paramagnetic is called the Curie temperature.
-
Ferri- and antiferromagnetism
Ferrimagnetism and antiferromagnetism are two magnetic properties of materials. In contrast to antiferromagnetic materials, ferrimagnetic materials are strongly attracted to a magnetic field. Paramagnetism, ferromagnetism and diamagnetism are other magnetic properties of matter.
-
Gauss
Gauss is a unit of magnetic flux density.
-
Gauss unit
The unit Gauss indicates the magnetic flux density. It was named after the well-known mathematician Johann Friedrich Gauss.
-
Hall probes
Hall probes (or Hall sensors) are devices that can be used to measure magnetic fields.
-
Magnetic North Pole
The magnetic north pole is located where the magnetic field lines of the earth's magnetic field enter the Earth's interior vertically to the earth's surface and therefore does not lie on the geographic North Pole.
-
Magnetic energy
Every magnetic field contains energy, also called magnetic energy. She is a constant in physics. Because a magnetic field is generated by electric currents, the magnetic energy is an energy form of moving charge carriers (electrons).
-
Magnetic flux density
The magnetic flux density is indirectly a measure for indexing the strength of a magnetic field.
-
Magnetic material
In our dictionary you will find an overview of all available magnetic materials.
-
Magnetic saturation
The maximum possible magnetization of a material is called saturation magnetization.
-
Magnetic tension
In electrodynamics, the term "magnetic stress" or "magnetic flux" is to be understood as a measure describing the excitatory force of the magnetic field strength.
-
Maxwell equations
The Maxwell equations combine all valid formulas for magnetic fields in one theory.

-
Oersted
The unit Oersted is used to measure magnetic fields (Unit H).
-
Operating temperature
The maximum temperature a magnet can withstand before it loses its magnetic properties.
-
Pauli principle
The Pauli Principle is a law in the field of quantum physics.
-
Physical Properties of Neodymium Magnets
Physical properties of neodymium magnets can be found in our glossary!
-
Right-hand rule
The right-hand rule (or three-finger rule) is an aid that illustrates vectors within a three-dimensional coordinate system.
-
Ring magnet
Ring magnets can be made of ferrite or neodymium or NdFeB (neodymium-iron-boron) and, like most magnets, have a nickel-plated coating to protect against oxidation. On the basis of their outside and inside diameter as well as the height they can be characterized more accurately and give information about adhesion, strength and Co.

Santoprene® belongs to the group of thermoplastic and elastic plastics.
-
Tesla (unit)
Tesla is a unit of magnetic flux density.
-
White districts
In magnetism, the term "delimited areas" of Weiss's districts (or white districts) is defined as having the same polarization.
-
coating
Magnets are often coated. There are several options for this.
-
coercivity
Magnetic coercivity is the magnetic field strength necessary to completely demagnetize a ferromagnetic substance.
-
diamagnetismus
Diamagnetism, together with para and ferromagnetism, describes various magnetic properties of matter.
-
dipole
Once two oppositely charged particles are present, it is called a dipole field.
-
electromagnetism
Electromagnetism is one of the fundamental forces of physics and has been intensively researched since its discovery by the physicist Oersted and later Michael Faraday and James Clerk Maxwell.
-
energy product
The energy product results from the magnetic flux density and the magnetic field strength of a magnet.
