Although magnetic fields interact weakly with biological tissues, at high fields, this interaction is sufficiently strong to cause measurable shifts in the Larmor frequency among various tissue types.
"The fact that magnetic fields interact so weakly with biological organisms is also important for safety considerations," Kurs, a graduate student in physics, points out.
Because magnetic fields interact much less strongly than electric fields with most types of matter including, most importantly, people the transmission of power would be both more efficient and considerably safer.
Eddy currents are generated when low frequency magnetic fields interact with conducting components and this, in turn, generates Lorentz forces, which can cause these metallic components to deform and vibrate.
There are various theoretical models of how this draping happens, and we think it's pretty important in determining where and when the magnetic fields interact.
When these alternating electric and magnetic fields interact with the polar molecules, these polar molecules are set into vibrations at the frequency of applied microwaves.
