Bearing compass A bearing compass is a magnetic compass mounted in such a way that it allows the taking of bearings of objects by aligning them with the lubber line of the bearing compass.

A compass deviation card is prepared so that the navigator can convert between compass and magnetic headings.

The effect of ferromagnetic materials in the compass's environment can be corrected by two iron balls mounted on either side of the compass binnacle.

A similar process is used to calibrate the compass in light general aviation aircraft, with the compass deviation card often mounted permanently just above or below the magnetic compass on the instrument panel.

Thus, the use of a magnetic compass by the military for land navigation occurred sometime before 1044, but incontestable evidence for the use of the compass as a maritime navigational device did not appear until 1117.

By carefully recording distances (time or paces) and magnetic bearings traveled, one can plot a course and return to one's starting point using the compass alone.

And that's magnetism.

What worries me is the compass.

Why the compass points to the North?

Why the compass point to the North?

Deviation refers to the response of the compass to local magnetic fields caused by the presence of iron and electric currents one can partly compensate for these by careful location of the compass and the placement of compensating magnets under the compass itself.

And they're called lodestones.

What are magnetic cores?

TS

A straightedge is to draw these lines. A compass is to draw these curves.

Golly, I'm just totally losing it.

We call this crustal magnetism.

And electric fields are not magnetism.

The magnetic rays no longer function.

Hourglass Since the hourglass was one of the few reliable methods of measuring time at sea, it is speculated that it was used on board ships as far back as the 11th century, when it would have complemented the magnetic compass as an aid to navigation.

Robotics.com Example implementation for digital solid state compass.

Are you sure your compass is right?

East, West. Points of the compass, each as stupid as the other.

The Saudi Ministry of Foreign Affairs has called the recent release of the leaked documents on WikiLeaks an electronic attack . The Saudi Ministry of Foreign Affairs warned Saudis on Twitter not to consider accessing the WikiLeaks site

For a table of the thirty two points, see compass points.

The compass can be corrected in three ways.

Refers to compass correction by Fourier series.

Albert Einstein was asking, why the compass point to the North?

Well you should have checked your compass before you smashed it.

We wouldn't have a chance. We need that compass.

They can sense the magnetic fields of the earth.

Magnetism always comes in the form of a dipole.

But with magnetism you always have a dipole.

Brothers and sisters know nothing of the points of the compass.

With the sun this high, it's pretty hard to tell the points of the compass.

They are also used in magnetic random access memories (MRAM).

TS Well, like the magnetically levitated objects

Maglev trains are utilized for long distance travel.

The junction of magnetic forces from the North to the South Pole!

Because when people first discovered these lodestones, or they took a lodestone and they magnetized a needle with that lodestone, and then that needle they put on a cork in a bucket of water, and that needle would point to the

It'll do this for weeks, until it kind of gradually loses the plot.
