  2. Bitter electromagnet - Wikipedia

    en.wikipedia.org/wiki/Bitter_electromagnet

    A Bitter electromagnet or Bitter solenoid is a type of electromagnet invented in 1933 by American physicist Francis Bitter used in scientific research to create extremely strong magnetic fields. Bitter electromagnets have been used to achieve the strongest continuous manmade magnetic fields on earth―up to 45 teslas , as of 2011 [update] .

    en.wikipedia.org/wiki/File:Electromagnet_with...

    The iron core of the electromagnet (C) forms a closed loop for the magnetic flux, with two air gaps (G) in it. Most of the magnetic field (B) is confined to the core circuit. However some of the magnetic field lines (B L ) take "short cuts" and do not pass through the entire core circuit and so do not contribute to the force exerted by the ...

  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 (likely copper) wound into a coil. A current through the wire creates a magnetic field which is concentrated along the center of the coil. The magnetic field disappears when the current is turned off.

  7. Electromagnetic spectrum - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_spectrum

    A diagram of the electromagnetic spectrum, showing various properties across the range of frequencies and wavelengths. The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band.

    en.wikipedia.org/wiki/Superconducting_magnet

    In 2007, a magnet with windings of YBCO achieved a world record field of 26.8 T. [13] The US National Research Council has a goal of creating a 30-tesla superconducting magnet. Globally in 2014, almost six billion US dollars worth of economic activity resulted from which superconductivity is indispensable.
