When the magnetic field oscillates, then a magnetic wave is produced-just like if you move the cone on a loudspeaker you get changes in air pressure-or sound waves.
32.
Whatever their cause, the magnetic waves, Goldstein said, " are just what is needed to scatter the cosmic rays, preventing many of them from getting in the solar system ."
33.
An RF signal falls off as 1 / " r ", whereas the strength of a magnetic wave falls off far faster at the rate of 1 / " r " ?
34.
Traditionally the magnetic wave would be generated either by physically moving a magnet or by an arrangement of coils switched in sequence, such as occurs on the stator of a three-phase motor.
35.
The team worked for two years off this city on Egypt's northern coast in waters 20 to 30 feet deep, using modern technology including the use of magnetic waves to map the area.
36.
A possible explanation for the magnetic waves, scientists suggested, is that the ends of the magnetic line of force attached to the Sun are being subjected to powerful churning motions of the Sun's surface.
37.
It has also sprinkled both borders with unattended sensors that detect seismic waves from ground motion and magnetic waves from vehicles, or that lay down infrared tripwires that sound alarms the moment they are broken.
38.
She said he was speaking very quietly, sounded agitated and confused, complaining that he no longer knew what was true and real, and that someone was conducting experiments with computers and magnetic waves, perhaps on him.
39.
All conductive surfaces of these orbiting laboratories and satellites, though, must be effectively bonded together to avoid differences of potential from being induced across their surfaces from the countless charged particles and magnetic waves traveling through space.
40.
Flux Pumping is a solid state method where a material which changes magnetic state at a suitable magnetic ordering temperature is heated at its edge and the resultant thermal wave produces a magnetic wave which then magnetizes the superconductor.
