Superconductors also repel all magnetic fields, which allows them to float in the air when they are placed
inside a strong magnetic field.

«Instead of a prolonged, comet - like tail, this rough bubble - shape of the heliosphere is due to the
strong interstellar
magnetic field — much
stronger than what was anticipated in the past — combined with the fact that the ratio between particle pressure and
magnetic pressure
inside the heliosheath is high,» said Kostas Dialynas, a space scientist at the Academy of Athens in Greece and lead author on the study.
NMR works by placing the sample of the protein to be studied
inside a device with a
strong magnetic field, and observing how they respond to different radio frequencies.
In the process, a
strong magnetic field is applied to food to magnetize the metal fragments
inside, and subsequently, these metals, if they are contained in the food, can be detected by sensing their
magnetic fields using SQUID sensors.
«These include different types of MRI scans, which use
strong magnetic fields and radio waves to produce detailed images of the
inside of the brain, and Positron Emission Tomography (PET) scans, which use a small amount of a radioactive drug, or tracer, to test how tissues in the brain are actually functioning.
The
strong magnetic fields inside these remnants accelerate protons to very high speed, creating cosmic rays.
