Sentences with phrase «together by magnetic fields»

One theory, proposed in the 1990s, suggests that ball lightning is a plasma held together by magnetic fields arranged in rings that link together into a knot.

Not exact matches

But apparently, the high and low - density lumps are partially bound together, most likely by magnetic fields linking distant clouds of gas and dust.

A combination of iron - oxide nanoparticles and an alternating magnetic field, which together generate heat, have activated an immune system response to tumors in mice according to an accepted manuscript by Dartmouth - Hitchcock Norris Cotton Center researchers in the journal Nanomedicine: Nanotechnology, Biology and Medicine released online on February 24, 2014.

External magnetic fields exert forces on them, levitate them against gravity and keep them together; the atoms are trapped in a magnetic cage with invisible walls formed by magnetic fields.

The cause, according to a theory advanced by PPPL physicist David Gates and colleagues at the Laboratory, lies in the tendency of bubble - like islands that form in the plasma that fuels fusion reactions to shed heat and grow exponentially — a runaway growth that disrupts the crucial current that completes the magnetic field that holds the plasma together.

«Interstellar clouds are permeated by magnetic fields that we believe to be effectively frozen to the contracting gas; as the gas cloud collapses to form a star, the magnetic field lines should be compressed ever closer together, giving rise to enormous magnetic fields, long before the collapse is completed.
