) This bellows configuration is used in aneroid barometers ( barometers with an indicating needle and dial card ), altimeters, altitude recording barographs, and the altitude telemetry instruments used in weather balloon radiosondes.

This display looks like a compass card with a needle superimposed, except that the card is fixed with the 0 degree position corresponding to the centreline of the aircraft.

Tamponade is treated by pericardiocentesis, the gentle insertion of the needle of a syringe into the pericardial sac ( avoiding the heart itself ) on an angle, usually from just below the sternum, and gently withdrawing the tamponading fluids.

A love of place, of the senses, and of life itself is represented by the pine needle forest floor — both at the beginning and, poignantly, at the end of the novel — when Robert Jordan awaits his death feeling " his heart beating against the pine needle floor of the forest.

Needle lace ( also known as needlelace or needle-made lace ) is a type of lace created using a needle and thread to stitch up hundreds of small stitches to form the lace itself.

When the needle is withdrawn the reservoir cover reseals itself.

It was inscribed with a spiral groove by the needle, which itself made a slow lateral movement across the belt.

The needle projectile has a very small mass, so its large change in velocity does not result in much recoil ( change in velocity of the gun itself ) since the gun has a mass much larger than the mass of the needle.

* If you drop a needle and it sticks itself into the ground, then someone is thinking ill of you.

This new type of German mine used a compass needle to detonate itself.

To reduce friction, the bridge was completed with rollers to allow the strings to return perfectly in tune after using the tremolo arm ( the arm itself was from a bicycle saddlebag holder with a plastic knitting needle tip ).

The tremolo-arm itself was made from a saddle bag carrier from an old bike and a knitting needle from his mother.

The Doctor inspects the hypodermic needle, and realises that it contained a neural inhibitor, which mimics a death-like state but does not cause death itself.

The piercing itself is usually made with a small gauge hollow piercing needle, and typical jewelry would be a small diameter captive bead ring or small gauge post style piercing jewelry.

The piercing itself is usually made with a small gauge hollow piercing needle, and typical jewelry would be a small diameter captive bead ring, or a stud.

Kutner, who has formed an emotional bond with the patient, explains to her adoptive parents that her alcoholism was caused by a needle which had embedding itself in the portion of her brain that controls addictive behavior.

While cosmetically it is virtually invisible, the scarring also occurs on the vein itself, making it harder to insert a needle on future occasions.

The piercing itself is made with a large gauge hollow piercing needle, and barbell jewelry is usually worn during the healing and stretching period.

Many people who suffer from fainting during needle procedures report no conscious fear of the needle procedure itself, but a great fear of the vasovagal syncope reaction.

An object such as a thumbtack or pen cover can stand on its base by itself, however an object such as a needle will need to be rooted in another stable object such as an eraser, sponge, box, or bottle cap in order to provide it with enough stability to hold the spinning wheel on its tip ; one design even uses a plastic bottle cap filled with an equal amount of J-B Weld, a two-part epoxy, to hold a needle upright in place.

At this lecture Oersted happened to place the conducting wire over and parallel to a magnetic needle.

In September of 1820, Ampère ’ s friend and eventual eulogist François Arago showed the members of the French Academy of Sciences the surprising discovery of Danish physicist Hans Christian Ørsted that a magnetic needle is deflected by an adjacent electric current.

The relation between electric current, magnetic fields and physical forces was first noted by Hans Christian Ørsted who, in 1820, observed a compass needle was deflected from pointing North when a current flowed in an adjacent wire.

As he was setting up his materials, he noticed a compass needle deflected from magnetic north when the electric current from the battery he was using was switched on and off.

In 1802 Gian Domenico Romagnosi, an Italian legal scholar, deflected a magnetic needle by electrostatic charges.

One of the most important discoveries relating to current was made accidentally by Hans Christian Ørsted in 1820, when, while preparing a lecture, he witnessed the current in a wire disturbing the needle of a magnetic compass.

Soon after the discovery in 1820 by H. C. Ørsted that a magnetic needle is acted on by a voltaic current, André-Marie Ampère that same year was able to devise through experimentation the formula for the angular dependence of the force between two current elements .< ref >

" The ancient Chinese scientist Shen Kuo ( 1031 – 1095 ) was the first person to write of the magnetic needle compass and that it improved the accuracy of navigation by employing the astronomical concept of true north ( Dream Pool Essays, AD 1088 ), and by the 12th century the Chinese were known to use the lodestone compass for navigation.

The Peltier electrometer, developed by Jean Charles Peltier, uses a form of magnetic compass to measure deflection by balancing the electrostatic force with a magnetic needle.

The deflection of a magnetic compass needle by current in a wire was first described by Hans Oersted in 1820.

Originally the instruments relied on the Earth's magnetic field to provide the restoring force for the compass needle ; these were called " tangent " galvanometers and had to be oriented before use.

It works by using a compass needle to compare a magnetic field generated by the unknown current to the magnetic field of the Earth.

It gets its name from its operating principle, the tangent law of magnetism, which states that the tangent of the angle a compass needle makes is proportional to the ratio of the strengths of the two perpendicular magnetic fields.

It consists of a tiny, powerful magnetic needle pivoted at the centre of the coil.

The magnetic needle is free to rotate in the horizontal plane.

In operation, the instrument is first rotated until the magnetic field of the Earth, indicated by the compass needle, is parallel with the plane of the coil.

These two perpendicular magnetic fields add vectorially, and the compass needle points along the direction of their resultant, at an angle of:

The battery is then connected and the rheostat is adjusted until the compass needle deflects 45 degrees from the geomagnetic field, indicating that the magnitude of the magnetic field at the center of the coil is the same as that of the horizontal component of the geomagnetic field.

The needle assembly is suspended by a silk thread, and has no net magnetic dipole moment.

The lower needle is inside the current sensing coils and is deflected by the magnetic field created by the passing current.

* In geology, the magnetic inclination is the angle made by a compass needle with respect to the horizontal surface of the Earth at a given latitude.

* 1802 — Gian Domenico Romagnosi notes that a nearby voltaic pile deflects a magnetic needle.

In their experiment they showed a connection between electricity and magnetism by " starting with a long vertical wire and a magnetic needle some horizontal distance apart showing that running a current through the wire caused the needle to move " ( Parsley ).
