Everything has a weak magnetic pull, which when exposed to a permanent magnet, can be made to levitate.
MRI, or magnetic resonance imaging, is a noninvasive means by which doctors get detailed visuals of the body's interior and are able to detect abnormalities.
Sockeye salmon are sensitive to Earth's magnetic pull. Scientists discovered that salmon use a trick called "geomagnetic imprinting" to find their way home.
Researchers are using transcranial magnetic stimulation to learn more about how magnetic fields affect areas of the brain associated with memory formation.
