  2. Photomagnetism - Wikipedia

    en.wikipedia.org/wiki/Photomagnetism

    Photomagnetism. The energy diagram of the transitions between the ground state and the magnetic state. Solid arrows represent absorption of photons and dashed arrows represent non radiative processes. Photomagnetism ( photomagnetic effect) is the effect in which a material acquires (and in some cases loses) its ferromagnetic properties in ...

  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. A permanent magnet is an object made from a material ...

  4. Electromagnet - Wikipedia

    en.wikipedia.org/wiki/Electromagnet

    An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil.

  5. 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 . The most familiar effects occur in ferromagnetic ...

  6. Magnetar - Wikipedia

    en.wikipedia.org/wiki/Magnetar

    Magnetar. A magnetar is a type of neutron star with an extremely powerful magnetic field (~10 9 to 10 11 T, ~10 13 to 10 15 G ). [1] The magnetic-field decay powers the emission of high- energy electromagnetic radiation, particularly X-rays and gamma rays. [2]
