Sentences with phrase «changing magnetic fields creates»

He observed that changing magnetic fields creates electric currents, and moving electric charges generates magnetic fields.

Not exact matches

This rotation, coupled with an ever - changing solar wind magnetic field, creates an extremely dynamic Martian magnetotail.

But whereas an MRI subjects materials to a magnetic field and measures how the polarity of the atoms in that material change, NDP hits materials with a low - energy neutron beam and counts the different kinds of charged particles that are created when an individual neutron happens to collide with one of the atoms in the test material and annihilates it.

After puzzling it over and practically wallpapering his house with seafloor topography and magnetic field maps, in 1993 Klimley hypothesized that somehow their oblong - shaped heads can sense tiny changes in the magnetic lines created by volcanic lava flows.

Changes in the atoms» spin rate correspond to an oscillation in the DC magnetic fields, creating alternating current (AC) electronic signals, or voltages at the light detector, which are more useful for communications.

Similarly, changes in the ambient magnetic field are created by submarines passing below the surface of the ocean, and the U.S. Navy is very interested in SQUIDs for submarine detection.

Given the corona is not expected to change much before the eclipse, scientists at the NSO used current observations to create a coronal magnetic model that shows where they expect to see field lines concentrated during the eclipse.

Regardless and most important, the mantle is slightly conductive, rapid changes in the core magnetic field would create currents in the mantle that would resist the changes.

Based on these observations and experiments, Harker and Pevtsov conclude that the observed magnetic transient is not an artifact created by the SDO / HMI observation process, but instead represents a real change in the vector magnetic field; since the active region was located so close to the solar limb, this suggests that the transient manifested in the horizontal component of the magnetic field (relative to the solar surface).

Undulators, with small and low field bending, create a narrower radiation cone with more intense beam, with selected wavelengths or harmonics, which can be tuned by manipulating the magnetic field of the device by changing the gap.
