The research team has identified atacamite as a material with magnetocaloric properties. Natural crystals have long ...

A new material developed at Penn State defies a fundamental law of physics, opening doors to highly efficient solar cells.

All types of magnetic fields - electronics, electric equipment and motors - can cause deviation. Deviation is different according to the boats heading. This often can be adjusted to a minimum. 4.

An Australian moth follows the stars during its yearly migration, using the night sky as a guiding compass, according to a new study.

Opinion: In this op-ed, retired Navy Capt. John Cordle shares why he chose to retire from his position as a federal worker ...

In general, these two references — magnetic and inertial — are aligned, or at least close enough that any difference, known as deviation, can be corrected. For 45 years, I followed my magnetic ...

Hence, only when a compass is roughly on a prolongation of the line from the geographical pole to the magnetic pole does it point true north.

The magnetic North Pole shifts and changes over time in response to changes in the Earth’s magnetic core. It is not a fixed point.

Note: Apple warns, " The accuracy of the compass can be affected by magnetic or environmental interference; even the magnets in the iPhone EarPods can cause a deviation. Use the digital compass only ...
