Little Big Coil: the record-breaking magnet is the size of a toilet roll core. (Courtesy: Stephen Bilenky/National MagLab) The highest continuous magnetic field ever created in the lab has been ...

Magnetic field due to current-carrying coil When a current flows in a wire, it creates a circular magnetic field around the wire. This magnetic field can deflect the needle of a magnetic compass.

Is more always better? Researchers sought to find out if that was the case for measuring magnetic field strengths. A new article examines whether a double H-coil method or a single H-coil method ...

Claimed to be the first-ever “magnetic field diode”, a device in which one wire coil can transfer its magnetic field to a second coil, but not the other way around has been created by Jordi Prat-Camps ...

The film demonstrates an experiment using an apparatus to observe the behavior of electrons in a uniform magnetic field. It explains how electrons are accelerated by an electron gun and then ...

On June 22, 2011, scientists at Helmholtz-Zentrum Dresden-Rossendorf set a new world record for magnetic fields with 91.4 teslas. To reach this record, the researchers developed a coil weighing ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Many migratory birds use Earth’s magnetic field as a compass, but some can also use information from that field to determine more or less where they are on a mental map. Eurasian reed warblers ...
