The magnetic field lines of a bar magnet can be viewed by using compasses or by shaking iron filings onto a platform above the magnet. Place the magnet on top of the paper in view of the document ...

A team of physicists and engineers at the University of Colorado Boulder has discovered a new way to measure the orientation ...

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 ...

The magnetic north pole, where compass needles point, is where geomagnetic field lines are vertical. As of this month, the distance between the magnetic dip pole and the geographic pole is about ...

Bar magnets and horseshoe magnets are two ... Iron is magnetic so the liquid iron causes Earth to have a magnetic field. The needle of a compass is a small magnet that can turn.

Because Earth's magnetic field is slightly asymmetrical and more complex than that of a regular bar magnet, the magnetic ... effectively a digital compass built into it," said William Brown ...

Instead, it aligns with Earth's magnetic field - and is the direction that a compass needle points to ... t regular like the field lines around a bar magnet. Instead, geological features push ...

This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...
