  2. Force between magnets - Wikipedia

    en.wikipedia.org/wiki/Force_between_magnets

    If the magnet is aligned with the magnetic field, corresponding to two magnets oriented in the same direction near the poles, then it will be drawn into the larger magnetic field. If it is oppositely aligned, such as the case of two magnets with like poles facing each other, then the magnet will be repelled from the region of higher magnetic field.

  3. Magnetic field - Wikipedia

    en.wikipedia.org/wiki/Magnetic_field

    If this H-field is the same at both poles of the second magnet then there is no net force on that magnet since the force is opposite for opposite poles. If, however, the magnetic field of the first magnet is nonuniform (such as the H near one of its poles), each pole of the second magnet sees a different field and is subject to a different force.

  4. 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.

  5. Dipole magnet - Wikipedia

    en.wikipedia.org/wiki/Dipole_magnet

    Magnetic field of a simple bar magnet. A dipole magnet is the simplest type of magnet.It has two poles, one north and one south. Its magnetic field lines form simple closed loops which emerge from the north pole, re-enter at the south pole, then pass through the body of the magnet.

  6. Magnetic levitation - Wikipedia

    en.wikipedia.org/wiki/Magnetic_levitation

    Magnetic materials and systems are able to attract or repel each other with a force dependent on the magnetic field and the area of the magnets. For example, the simplest example of lift would be a simple dipole magnet positioned in the magnetic fields of another dipole magnet, oriented with like poles facing each other, so that the force ...

  7. Magnet - Wikipedia

    en.wikipedia.org/wiki/Magnet

    A magnet is a material or object that produces a magnetic field.This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.

  8. Magnetic dipole - Wikipedia

    en.wikipedia.org/wiki/Magnetic_dipole

    All generate the same field profile when the arrangement is infinitesimally small. [1] In electromagnetism, a magnetic dipole is the limit of either a closed loop of electric current or a pair of poles as the size of the source is reduced to zero while keeping the magnetic moment constant.

  9. Diamagnetism - Wikipedia

    en.wikipedia.org/wiki/Diamagnetism

    Diamagnetism is the property of materials that are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force.
