Low-frequency magnetic fields induce circulating currents within the human body. The strength of these currents depends on the intensity of the outside magnetic field. If sufficiently large, these currents could cause stimulation of nerves and muscles or affect other biological processes.Aug 4, 2016

Does magnetic field affect human body?
The Earth's magnetic field does not directly affect human health. Humans evolved to live on this planet. High altitude pilots and astronauts can experience higher levels of radiation during magnetic storms, but the hazard is due to the radiation, not the magnetic field itself.
How do strong magnetic fields affect the human body?
The intense fields used by medical scanners, which are around 100,000 times stronger than the Earth's magnetic field, can trigger nausea, dizziness and a metallic taste in the mouth, but these effects are temporary.
How do magnetic fields affect the human brain?
So, applying a magnetic field will cause current to flow through the neurons and this can alter their activity. To alter the activity of neurons, the electric field must be strong enough to generate an electrical current in the neurons as well as in the synapses in between them [1].
Can magnets damage the brain?
Prolonged exposure to low-level magnetic fields, similar to those emitted by such common household devices as blow dryers, electric blankets and razors, can damage brain cell DNA, according to researchers in the University of Washington's Department of Bioengineering.
What happens if the magnetic field weakens?
If Earth lost its magnetic field, there would be no magnetosphere – and no line of defense, even from weaker solar storms. Our power grids would be more vulnerable than ever, and even our computers and other electronics could suffer damage if a solar storm struck.
Can magnets heal the body?
Magnets have no healing properties. Magnetic Resonance Imaging (MRI) employs very strong magnetic fields, far stronger than a household magnet can produce, and yet MRI's have no direct effect on the health of the patient (an MRI may have an indirect effect as a diagnostic tool).
Do magnets affect blood?
Researchers show that magnetic fields can reduce blood viscosity, a leading cause of heart attack and strokes. Two physicists searching for a novel way to prevent heart attacks and strokes have discovered that strong magnetic fields can dramatically reduce the thickness, or viscosity, of blood flowing through a tube.
How do magnets heal the body?
Restoration of cellular magnetic balance. Migration of calcium ions is accelerated to help heal bones and nerve tissues. Circulation is enhanced since biomagnets are attracted to the iron in blood and this increase in blood flow helps healing. Biomagnets have a positive effect on the pH balance of cells.
What happens when the Earth’s magnetic field reverses?
During a pole reversal, the magnetic field weakens, but it doesn't completely disappear. The magnetosphere, together with Earth's atmosphere, continue protecting Earth from cosmic rays and charged solar particles, though there may be a small amount of particulate radiation that makes it down to Earth's surface.
