  2. Magnetic field - Wikipedia

    en.wikipedia.org/wiki/Magnetic_field

    The magnetic field of larger magnets can be obtained by modeling them as a collection of a large number of small magnets called dipoles each having their own m. The magnetic field produced by the magnet then is the net magnetic field of these dipoles; any net force on the magnet is a result of adding up the forces on the individual dipoles.

  3. 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.

  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. Earth's magnetic field - Wikipedia

    en.wikipedia.org/wiki/Earth's_magnetic_field

    A magnetic field is a vector field, but if it is expressed in Cartesian components X, Y, Z, each component is the derivative of the same scalar function called the magnetic potential. Analyses of the Earth's magnetic field use a modified version of the usual spherical harmonics that differ by a multiplicative factor.

  6. Force between magnets - Wikipedia

    en.wikipedia.org/wiki/Force_between_magnets

    Magnetic pole model for H and Ampèrian loop model for B yield the identical field outside of a magnet. Inside they are very different. The field of a magnet is the sum of fields from all magnetized volume elements, which consist of small magnetic dipoles on an atomic level.

  7. Demagnetizing field - Wikipedia

    en.wikipedia.org/wiki/Demagnetizing_field

    The demagnetizing field, also called the stray field (outside the magnet), is the magnetic field (H-field) [1] generated by the magnetization in a magnet.The total magnetic field in a region containing magnets is the sum of the demagnetizing fields of the magnets and the magnetic field due to any free currents or displacement currents.

  9. Magnetization - Wikipedia

    en.wikipedia.org/wiki/Magnetization

    The magnetization field or M-field can be defined according to the following equation: =. Where is the elementary magnetic moment and is the volume element; in other words, the M-field is the distribution of magnetic moments in the region or manifold concerned.
