the earth has a magnetic field that is essentially anchored by two poles -- magnetic north and magnetic south. A compass uses ...

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 ...

In a recent paper published in National Science Review, researchers developed a bottom-up approach for magnetic regulation of ...

It's better to anticipate a longer route than a shorter one. The compass consists of a magnetized metal needle that floats on a pivot point. The needle orients to the magnetic field lines of the earth ...

As Ron Merrill, a magnetic-field specialist at the University of ... So hang on to your compass. For the foreseeable future, it should work as advertised.—Peter Tyson ...

scientists have found clues to how birds sense the Earth's magnetic field. Just as you might reach for a magnetic compass to find which way is north or south, birds are thought to have an in-built ...

The strength of a coupling between nuclear spins depends on chirality, or handedness, of the molecule, according to a new ...

The magnetized needle in a compass can detect very slight magnetic fields. No matter where you stand on Earth, you can hold a compass in your hand and it will point toward the North. This is ...

Compasses aren't just for survival, they're also fun! Here's how use one. The post How To Use a Compass When Camping appeared ...

Flux-gate / Coil The instrument performs a continuous measurement of the differences in the magnetic field at the ends of a vertical rod and plots these on a grid of the area. It is widely used in ...

If you need help visualizing magnetic fields, these slow-motion video captures should educate or captivate you. Flux lines are difficult to describe in words, because magnet shape and strength ...
