Topic: Magnetic pickup

	Bass guitar - Wikipedia, the free encyclopedia
		The vibrations of the instrument's metal strings within the magnetic field of the permanent magnets in the pickups, produce small variations in the magnetic flux threading the coils of the pickups.
		Another unusual pickup configuration is found on some of the custom basses that Billy Sheehan uses, where the pickups are found on the neck of the bass, replacing the fret markers.
		The placement of the pickup greatly affects the sound, with a pickup near the neck joint thought to sound "fatter" or "warmer" while a pickup near the bridge is thought to sound "tighter" or "sharper." Most basses with multiple pickups allow blending of the output from the pickups, providing for a range of timbres.

	Pickup (music) - Wikipedia, the free encyclopedia
		A pickup device acts as a transducer that captures mechanical vibrations (usually from suitably equipped stringed instruments such as the electric guitar, electric bass guitar or electric violin) and converts them to an electronic signal which can be amplified and recorded.
		A magnetic pickup consists of a permanent magnet wrapped with a coil of a few thousand turns of fine copper wire.
		Electromagnetic pickups are usually designed to feed a high input impedance, typically a megaohm or more and a low impedance load will reduce the high-frequency response of the pickup because of the filtering effect of the inductance.

	Magnetic pickup for musical instruments - Patent 5290968
		Magnetic pickups are typically mounted on the body of the instrument, such as guitar, beneath the strings and at one or more points between the bridge and the neck of the guitar.
		1, a magnetic pickup in accordance with the present invention is positioned beneath the strings 34 of a stringed instrument, such as an electric guitar, and is fastened to the body of the instrument by means of fastening holes 30.
		Further, the magnetic pickup comprises AC output terminals 28, by means of which the output of the individual pickups 16 is preferably sent to an outboard amplification device where the signal is boosted and sent to a speaker wherein the signal is converted to sound.

	Pickup Response Demonstration Applet
		The table at the bottom has a set of controls for each pickup; the pickup position (in inches from the bridge), the pickup magnetic aperture width (in inches), the pickup level (in dB) both as a value and as a slider control, the polarity of the pickup, and a button to remove that pickup.
		One of the combs is due to the position of the pickup, the distance the pickup is from the bridge while the other is due to the width of the pickup.
		Ie., the curve for a pickup 4.0 inches from the bridge ought to be the same as the curve for a pickup 4.0 inches from the nut.

		When using the magnetic pickup for TDC (top dead center) triggering in reciprocating machine analysis, it is extremely important that the pickup triggers data acquisition exactly at TDC.
		Zero-crossing occurs at the magnetic center of the magnetic pickup or when the magnetic pickup is centered on the target.
		When the magnetic field changes due to the pickup going over a hole or object, a voltage is generated in the coil.

	Capgo - Magnetically Induced Noise
		Magnetically induction is the most frequent method by which noise is introduced to a measurement setup.
		The principal of magnetic induction is simple - a voltage is induced into any conductor that is, either passed through a magnetic field, or morel commonly is exposed to a changing magnetic field.
		The magnitude of the voltage is proportional to the rate of change of the magnetic field and the area of the conduct loop.

	Daytronic Corporation - High-Sensitivity Magnetic Pickup
		In properly designed flowmeters, the output frequency produced by the magnetic pickup is a linear function of the volumetric flow rate.
		A magnetic pickup may also be used as a timing or synchronization device—as, for example, in ignition timing of gasoline engines, angular positioning of rotating parts, or stroboscopic triggering of mechanical motion.
		The Model MP1A Magnetic Pickup is a fast, general-purpose sensor, providing an effective, accurate means of measuring the speed and frequency of mechanical rotary motion without the necessity of mechanical linkage—and the contact, wear, cabling, and alignment problems such linkage entails.

	Magneteic Spot Pickups from Experimental Musical Instruments
		Electromagnetic pickups are most commonly used in electric guitars, but they can be used equally well in any instrument in which the vibrating element is made of steel or other ferrous metal.
		Thus, this pickup can be used for instruments using steel strings, as well as mbira- or kalimba-like instruments with iron or steel tines, xylophone-like instruments with steel bars or tubes, and many others types.
		For installations that call for large numbers of pickups, you can preserve signal strength and frequency response by wiring the pickups in two or more sub-groups which are buffered from one another by sending their signals to separate mixer inputs or separate in-line pre-amps before mixing the signals.

	GuitarNuts.com - How Magnetic Pickups Work
		However, pickups are said to be "in-phase" when their signals are in phase (the signal generated in one pickup adds to the signal generated in the other, instead of subtracting from it).
		Thus, you can use a switch to control how the pickup is wiredby switching between series/parallel wiring for the two coils or using either coil of the pickup as a single coil, etc. This is another case where practice doesn't quite live up to theory.
		How "hot" the pickup will be depends primarily on two variables; how strong the magnet is, and how many turns of wire are on the coil.

	Bill Lawrence Website
		The main component of a magnetic pickup is a cored inductor -- a coil of insulated wire with a ferromagnetic core.
		Hum-canceling pickups were first introduced in the thirties, but at the low volume levels used at that time, hum was not yet a problem.
		Remember, a pickup is NOT a power generator, and the magnitudes of volts, amps and watts are extremely small; but, regardless how many turns you put on a pickup, you will NEVER get 100 watts out of a 50 watt amp.
