Magnetic fields of 3 teslas or greater are often needed for the initial magnetization step of NDR.

Refrigerators based on the magnetocaloric effect have been demonstrated in laboratories, using magnetic fields starting at 0. 6 T up to 10 T. Magnetic fields above 2 T are difficult to produce with permanent magnets and are produced by a superconducting magnet ( 1 T is about 20, 000 times the Earth's magnetic field ).

* Pigeons Detect Magnetic Fields An experiment indicating that the trigeminal nerve, in the species Columba livia may be the mechanism through which " homing pigeons " detect magnetic fields

Magnetic ( compass ) north and geographic ( true ) north are only exactly the same for a small number of places – for example, as of 2000 in the United States only those places on a line running from Wisconsin to the Gulf of Mexico .< ref > But the public may not be as informed, and think there is something mysterious about a compass " changing " across an area as large as the Triangle, which it naturally will.

Magnetic flux from the surroundings ( such as other wires ) may diminish or enhance the field the Hall probe intends to detect, rendering the results inaccurate.

A live frog is Magnetic levitation | magnetically levitated, an experiment that earned Andre Geim from the University of Nijmegen and Sir Michael Berry ( physicist ) | Michael Berry from University of Bristol the 2000 Ig Nobel Prize in physics.

The Finnish Meteorological Central Office ( 1881 ) was formed from part of Magnetic Observatory of Helsinki University.

* " Mad ", a song by Magnetic Man from the album Magnetic Man

In May 1845 the Magnetic Telegraph Company was formed in order to radiate telegraph lines from New York City towards Philadelphia, Boston, Buffalo, New York and the Mississippi.

Magnetic tape or disk " card-image " files created from such card decks often had no line-separation characters at all, commonly assuming fixed-length 80-character records.

Values used by mobile stations usually need to be converted from Magnetic to True.

Magnetic field lines, represented as arrows, are excluded from a superconductor when it is below its critical temperature.

Image: Tin_80gauss_1. 6K. jpg | The cylinder has been cooled from 4. 2 K to 1. 6 K. The current in the electromagnet has been kept constant, but the tin became superconducting at about 3 K. Magnetic flux has been expelled from the cylinder ( the Meissner effect ).

Satellite, near-surface and oceanic data from detectors was used to create the World Digital Magnetic Anomaly Map published by the Commission for the Geological Map of the World ( CGMW ) in July 2007.

The show included two tracks from the then-forthcoming Scratch My Back: Paul Simon's " The Boy in the Bubble " and The Magnetic Fields ' " The Book of Love ".
