This magnetic cycle lasts approximately 22 years, through which the sun's magnetic field reverses and then reverts to its original state, Ryan French, a solar astrophysicist and Space.com ...

The earth’s magnetic field is about 0.05mT, or 0.5G. Magnetic measurements in household and work environments demonstrate measurements below 0.1mT, or 1G, at distances greater than 16cm, ...

According to the ESA, “Our magnetic field is largely generated by an ocean of superheated, swirling liquid iron that makes up the outer core around 1,864 miles beneath our feet.

Sometimes, the magnetic fields are relatively weak, like the ones that thread their way through the spiral arms of galaxies. Sometimes, they're medium-strength, like Earth's.
