Earth is surrounded by a magnetic field generated by electric currents from within the planet. Compasses take advantage of this field to identify north and serve as a navigational aid. But one social ...

Scientists have developed a way to produce models of where the magnetic field lines are several times each day. Here we have created a time-lapse version of these models over four days (2-3 each day) ...

The concept of magnetic field lines and magnetic fields was first studied and observed by Michael Faraday and by James Clerk Maxwell, who made great discoveries in the field of electromagnetism.

The updated version of the World Magnetic Model was released on Dec. 17, with a new prediction of how the magnetic north pole will shift over the next five years. Here's why it was changed. When you ...

Migratory bats use a magnetic sense to navigate long distances, calibrating their internal compass based on the position of the setting sun each evening. Many animals may use Earth’s magnetic field ...

The weak spot in Earth’s magnetic field, a region over the South Atlantic where the field’s strength is significantly reduced compared to its surrounding area, has grown by an area nearly the size of ...

In 2008, Erez Ben-Yosef unearthed a piece of Iron Age "trash" and inadvertently revealed the strongest magnetic-field anomaly ever found. Ben-Yosef, an archaeologist at Tel Aviv University, had been ...

A new image from the VLA dramatically reveals the extended magnetic field of a spiral galaxy seen edge-on from Earth. A new image shows the huge extent of a spiral galaxy's magnetic field. The galaxy ...
