  2. Force between magnets - Wikipedia

    en.wikipedia.org/wiki/Force_between_magnets

    Calculating the attractive or repulsive force between two magnets is, in the general case, a very complex operation, as it depends on the shape, magnetization, orientation and separation of the magnets. The magnetic pole model does depend on some knowledge of how the ‘magnetic charge’ is distributed over the magnetic poles.

  3. Magnetism - Wikipedia

    en.wikipedia.org/wiki/Magnetism

    Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.

  4. Earnshaw's theorem - Wikipedia

    en.wikipedia.org/wiki/Earnshaw's_theorem

    Earnshaw's theorem has even been proven for the general case of extended bodies, and this is so even if they are flexible and conducting, provided they are not diamagnetic, [2] [3] as diamagnetism constitutes a (small) repulsive force, but no attraction. There are, however, several exceptions to the rule's assumptions, which allow magnetic ...

  5. Non-contact force - Wikipedia

    en.wikipedia.org/wiki/Non-contact_force

    All four known fundamental interactions are non-contact forces: [2] Gravity, the force of attraction that exists among all bodies that have mass. The force exerted on each body by the other through weight is proportional to the mass of the first body times the mass of the second body divided by the square of the distance between them.

  6. Fundamental interaction - Wikipedia

    en.wikipedia.org/wiki/Fundamental_interaction

    Nothing "cancels" gravity, since it is only attractive, unlike electric forces which can be attractive or repulsive. On the other hand, all objects having mass are subject to the gravitational force, which only attracts. Therefore, only gravitation matters on the large-scale structure of the universe.

  7. Electromagnetism - Wikipedia

    en.wikipedia.org/wiki/Electromagnetism

    Electromagnetic forces occur between any two charged particles. Electric forces cause an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs between charged particles in relative motion. These two forces are described in terms of electromagnetic ...

  8. Biomagnetism - Wikipedia

    en.wikipedia.org/wiki/Biomagnetism

    Biomagnetism is the phenomenon of magnetic fields produced by living organisms; it is a subset of bioelectromagnetism. In contrast, organisms' use of magnetism in navigation is magnetoception and the study of the magnetic fields' effects on organisms is magnetobiology. (The word biomagnetism has also been used loosely to include magnetobiology ...

  9. Ampère's force law - Wikipedia

    en.wikipedia.org/wiki/Ampère's_force_law

    In magnetostatics, the force of attraction or repulsion between two current-carrying wires (see first figure below) is often called Ampère's force law. The physical origin of this force is that each wire generates a magnetic field , following the Biot–Savart law , and the other wire experiences a magnetic force as a consequence, following ...
