Birdcage RF coil Questions and Answers in MRI
Generation of rotating B1 field (green arrow) by a birdcage coil. Sinusoidal current is applied sequentially to rungs 1-6, each of which generates a local field in directions shown. A phase shift of 360/6 = 60 between the successive rungs produces a resonantly rotating B1 field.

Magnetic field in an AC Solenoid Coil Physics Forums
Jun 11, 2009hi chitrageetam, you said you are working on an AC Solenoid.. of course the field and the current depend upon the frequency.. the current that flows through the solenoid coils depends upon the voltage from the mains and the impedance of the coil..
MRI Coil Laboratory University of Washington
A radio frequency (RF) receiver coil picks up both the MR signal, which is a weak oscillating magnet field from the rotating hydrogen nuclei in the patient, and the noise, which is due to the random motion of charged particles in the imaging system.

Main menu. it needed both the 7.83 Hz signal as well as the even lower frequency that comes from earth itself, about 0.5 Hz. When the coil is directly against your skin, you are getting over 100 milligauss or more of magnetic energy
Probes Mode of Operation
Probes Mode of Operation. The eddy currents generate their own magnetic field that opposes the magnetic field of the coil and this changes the inductive reactance of the coil. By measuring the absolute change in impedance of the test coil, much information can be gained about the test material. there is no differential signal
Guitar Pickups Explained (Guitarsite)
Where does the electric guitar signal come from? Pickups are transducers that convert the mechanical energy of a vibrating guitar string into electrical energy by way of electromagnetic induction. It is a fundamental concept studied in physics and electronics that a changing magnetic field will generate a current through a coil of wire.

Center for NMR Spectroscopy The Lock
The lock unit can also be said to be a component of the shim system as the lock signal is the most often used criterion for adjustment of the magnetic field. In short the lock unit is for all intents and purposes a self contained mini-NMR which measures most often the resonance position of deuterium.
