A quadrupole itself is an orientation of metal rods that filter mass ions by alternating current, creating a stable oscillation (and hence, transmission) of a "band" of a selected m/z ions.
They turned on an alternating current in the coil, creating an alternating magnetic field.
The primary difference between wired and wireless networks is that wireless networks use a special type of electric current known as radio frequency (RF), which is created by applying alternating current to an antenna to produce an electromagnetic (EM) field.
This vibration creates an alternating current that can be tapped.
An alternating current applied to the stator's windings creates a rotating magnetic field, while simultaneously inducing a current in the separate conductors surrounding the rotor.
Wind turbines produce alternating current.
With alternating current the polarity changes over 100 times per second, creating an even heat distribution and providing a balance between electrode melting rate and penetration.
For creating appropriate surfaces with asymmetric roughness, electropolished aluminium samples were electrograined by alternating current (AC) in hydrochloric acid.
Powered by standard alternating current or battery, it runs electricity through a wire that is coiled around a metal cylinder, creating a harmless, low-energy magnetic field that extends for hundreds of meters.
It involves playing with the nature of alternating current.
