In MRI, a patient lies in a large cylinder that is equipped with a powerful magnet, a radio wave emitter, and a radio wave detector. Particles in the bones and soft tissues behave like tiny magnets and can be lined up. When the MRI machine causes the orientation of the particles to flip, they produce radio waves. The released energy is detected by the radio receiver and used to create a map of the different tissues.
Brass instruments involve the blowing of air into a mouthpiece. The vibrations of the lips against the mouthpiece produce a range of frequencies. ... This forces the air inside of the column into resonance vibrations. The result of resonance is always a big vibration - that is, a loud sound.
Nuclear Magnetic Resonance Imaging (NMRI) is a commonly used in medicine and other specialized applications. NMRI can produce in high detail three-dimensional images of organs and other internals.
emi in electronics is electro-magnetic interference. I do not know of any advantage as it always interferes. A high db reading of emi shielding is good. Electro-magnetic waves are present everywhere and the problem is keeping them out of our electronics as best as we can. An additional problem is that all electronics produce electro-magnetic fields.
A neutron star contains a powerful magnetic field and spins very rapidly. the spinning magnetic field generates a tremendously powerful electric field, and the filed causes the production of electron positron pairs. As the charged particles are accelerated through the magnetic field, they emit photons in the direction of their motion, which produce powerful beams of electromagnetic radiation emerging from the magnetic poles. Pretty much when you look at it from far away it looks like it blinking at you so that's why they call it the light house model in the same way when your at sea and you see a blinking light in the distance which is a lighthouse. =)
No way man....res heads need to vibrate to produce a full sound, the batter heads are made thicker so they won't vibrate.
This process is called magnetic resonance imaging, or MRI.

Magnetic resonance imaging or MRI is commonly used in the medical field. This technique can be used to produce a detailed image of almost any part of the human body, assisting greatly with diagnosis.
Computerized axial tomography (CT or CAT) scans use a rotating x-ray beam to obtain pictures. Magnetic resonance imaging (MRI) uses magnetic fields and radio waves to produce images of the body.
Functional Magnetic Resonance Imaging (fMRI)
Magnetic resonance imaging, or MRI, is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. Sometimes a contrast solution is injected into the patient during the MRI scan to show certain structures more clearly.
