This tube is known as the bore. But this isn't just any magnet -- we're dealing with an incredibly strong system here, one capable of producing a large, stable magnetic field. The strength of a magnet in an MRI system is rated using a unit of measure known as a tesla. Another ...
Magnetic and electrical fields are related, and magnetism, along with gravity and strong and weak atomic forces, is one of the four fundamental forces in the universe. But none of those facts answers the most basic question: What exactly makes a magnet stick to certain metals? Or why don't...

If you want, you can make an electromagnet by wrapping wires around a used paper towel roll, but if you want a strong magnet, wrap them around an iron core instead. Iron is a magnetic material, and it becomes magnetized when you switch on the current. This gives you, in effect, two ...
"We believe the risk to patients is low. … However, the number of consumer electronics with strong magnets is expected to increase over time," Dr. Jeff Shuren, director of the Food and Drug Administration's medical device division, said in a statement following a broad study by the agency...
Recalling Faraday’s law of electromagnetic induction, that spinning, positively charged hydrogen nucleus is essentially a moving charge or current, which induces a magnetic field or tiny magnetic dipole. Normally, hydrogen dipoles are oriented randomly. However, when placed in a strong external ...
Another promising avenue for exploration pertains to the therapeutic applications of music. While the existing literature, as summarized in this review, posits a strong case for music as a potent therapeutic tool, the exact protocols, durations, and modalities through which optimal therapeutic outcomes...
Strong leg muscles help protect your knee and prevent strain. The following may also prevent a knee sprain:Slowly start your exercise or training program. Slowly increase the time, distance, and intensity of your exercise. Sudden increases in training may cause another knee sprain. Wear protective...
The basic stages of an MRI reading are simple. First the patient is placed in a strong constant magnetic field and is surrounded by several coils. Radiofrequency (RF) radiation is then applied to the system, causing certain atoms within the patient to resonate. When the RF radiation is ...
where spin relaxation is dominated by EY mechanism, the same as in CsPbBr3. The cause of such strongnc-dependence at lowTis discussed below in more details, attributing tonceffects on (averaged) spin-flip matrix elements. As a result, at lowTand lownc,τsof CsPbBr3can be rather long, ...
