A magnet's magnetic moment (also called magnetic dipole moment and usually denoted μ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, [ 15 ] and the magnitude relates to how strong and how far apart these poles ...
In 2016, Yoon et al. reported a 26 T no-insulation superconducting magnet that they built out of GdBa 2 Cu 3 O 7–x, [15] using a technique which was previously reported in 2013. [16] In 2017, a YBCO magnet created by the National High Magnetic Field Laboratory (NHMFL) broke the previous world record with a strength of 32 T.
The magnetic field lines of a current-carrying loop of wire pass through the center of the loop, concentrating the field there. Magnetic field generated by passing a current through a coil. An electric current flowing in a wire creates a magnetic field around the wire, due to Ampere's law (see drawing of wire with magnetic field).
