But today, without a global magnetic field to guide it, a compass on the Moon would be useless. This small, rocky planet has a weak but detectable global magnetic field, only about 1 percent the ...

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have developed an innovative method ...

A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction ...

Until the arrival of GPS, the magnetic compass was the single most useful navigational tool ... and birds—are able to orient themselves relative to the Earth’s magnetic field. Among mammals, naked ...

Such reversals in the Earth's magnetic field, they'd tell you ... So hang on to your compass. For the foreseeable future, it should work as advertised.—Peter Tyson ...

Primarily, the compass was used for geomancy for a long time before it was used for navigation Ancient Chinese alchemists realized that the magnetite ore would point towards a magnetic north. Their ...

Over a two-month conditioning period, the study team placed the turtles in small ... field — researchers tested whether the turtles could still detect their magnetic map and magnetic compass.

This "nano-compass" allows the microbe to passively orient itself in Earth's geomagnetic field (Figure 2). These magnetic nanoparticles are synthesized by a specific set of proteins that are ...
