Magnetometers can detect only magnetic ( ferrous ) metals, but can detect such metals at a much larger depth than a metal detector ; magnetometers are capable of detecting large objects, such as cars, at tens of meters, while a metal detector's range is rarely more than 2 meters.

Magnetometers can measure the magnetic fields of planets.

Magnetometers can give an indication of auroral activity before the light from the aurora becomes visible.

Magnetometers can be divided into two basic types:

Magnetometers can also be classified as " AC " if they measure fields that vary relatively rapidly in time, and " DC " if they measure fields that vary only slowly ( quasi-static ) or are static.

Magnetometers used in the Earth sciences are called geophysical surveys, a term that also embraces a wide range of other geophysical techniques including gravity, seismic refraction, seismic reflection, electromagnetics ( EM ), induced polarisation ( IP ), magneto-tellurics ( MT ), controlled source magneto-tellurics ( CSAMT ), sub-audio magnetics ( SAM ), mise-a-la-masse, resistivity, self Potential ( SP ) and Very Low Frequency ( VLF ).

Magnetometers are also used to detect archaeological sites, shipwrecks and other buried or submerged objects.

Magnetometers are also a component instrument on the Mercury MESSENGER mission.

Magnetometers may also use a variety of different sensor types.

Magnetometers such as the German Forster are used to locate ferrous ordnance.

Magnetometers are one of the primary tools used to locate world-class deposits of gold, silver, copper, iron, tin, platinum and diamonds.

Magnetometers assist mineral explorers both directly ( i. e. gold mineralisation associated with magnetite, diamonds in kimberlite pipes ) and, more commonly, indirectly, such as by mapping geological structures conducive to mineralisation ( i. e. shear zones and alteration haloes around granites ).

Magnetometers are distinct from metal detectors, which detect metallic objects by detecting their conductivity.

Airborne Magnetometers detect the change in the earth's magnetic field using sensors attached to the aircraft in the form of a " stinger " or by towing a magnetometer on the end of a cable.

Magnetometers detect minute deviations in the Earth's magnetic field caused by iron artifacts, kilns, some types of stone structures, and even ditches and middens in archaeological geophysics.

Magnetometers measure minute differences in the magnetic field of the earth caused by ferrous concentrations ( and iron objects ) in the soil, thermo-remnant magnetism of fired clays, and differences in the magnetic susceptibility of disturbed soils.

Magnetometers have a very diverse range of applications, including locating objects such as submarines, sunken ships, hazards for tunnel boring machines, hazards in coal mines, unexploded ordnance, toxic waste drums, as well as a wide range of mineral deposits and geological structures.

Magnetometers used in geophysical survey may use a single sensor to measure the total magnetic field strength, or may use two ( sometimes more ) spatially separated sensors to measure the gradient of the magnetic field ( the difference between the sensors ).

And though we can look back now and see their errors, we can look back also to the ultimate error.

We can also argue that the three brothers Karamazov and Smerdyakov were the external representatives of an internal conflict within one man, Dostoevsky, a conflict having to do with father-murder and the wish to possess the father's woman.

And if we understand the rocking as an erotic symbol we can also see how well it serves as the symbol of impending tragedy.

One of the early humorists already mentioned, Thomas Bangs Thorpe, can be used to illustrate another point where Faulkner touches authentic Southern materials and also earlier literary treatment of those materials.

It is, however, a disarming disguise, or perhaps a shield, for not only has Mercer proved himself to be one of the few great lyricists over the years, but also one who can function remarkably under pressure.

And we can add that Krutch's interpretation of purgation is also one answer to Plato's fear that poetry will encourage our passions.

Of course I hope Hal can also, but those hopes are much more faint ''.

At Khrushchev's door, therefore, can be placed the primary blame but also at fault are those who permitted themselves to be intimidated.

It has also been observed, in helium 2, that large discrepancies can exist between surface vapor pressures and those pressures measured by a vapor pressure thermometer.

In this case also the design of the thermometer can be modified to reduce the helium film flow.

I also hope that we can do something about reducing the infant mortality rate of ideas -- an affliction of all bureaucracies.

Steps should also be taken to link the Food for Peace Program with the Peace Corps, so that foreign currencies accumulated by the sale of U.S. surplus food under P.L. 480 can be put to use to pay some of the host country expenses of Peace Corps personnel.

It can also contribute to the education of America and to more intelligent American participation in the world.

The president has little influence in day-by-day curricular changes, but if he looks ahead two, three, or five years to anticipate issues and throw out challenging ideas, he can open the way for innovation, and he can also have a great deal to say as to what path it will take.

But as you can also see, it's not a painful exercise at all, because Henri De Courcy -- the `` happy '' bodybuilder -- looks as though he were having the time of his life!!

The aircraft could be used to destroy other mobile, fleeting, and imprecisely located targets as well as the known, fixed and hardened targets which can also be destroyed by missile.

The Rio Grande KC is also considering having their Junior Classes set up so that Juniors can qualify with points for Westminster.

These can also move a short distance but at right angles to the tappets.

This tool can also be made with a lathe.

The most intriguing aspect of the S & W Magnum chambered for the new Jet is that it can also fire standard

With them, you can carry steaks and hamburgers at refrigerator temperatures, and also get your frozen food for stews and chowders, to the marina or picnic, in A-1 condition.

You can also see that the greater the proximity of the pool to your main living quarters, the greater the chance for violation of family privacy, annoying noise and the let's-make-your-house-our-club attitude.

Our pools also have wide, shallow steps -- for the benefit of the littlest swimmers who can thus be introduced to the water with far greater safety than a ladder affords.
