The field can point in any direction, whether Up, Down, North, South, or anywhere in between, and can simulate the local magnetic field in the Northern or Southern Hemisphere. The field is very weak (35 microTesla), comparable to what we experience in our laboratory outside the test chamber, and 100,000 times weaker than in a research MRI (4 Tesla).

Difference Between Magnetic Field and Magnetic Flux

Oct 07, 2015Main Difference Magnetic Field vs. Magnetic Flux. Magnetic field and magnetic flux both refer to properties of magnets. The main difference between magnetic field and magnetic flux is that magnetic field is a region where magnetic poles and moving charges experience a force.Sometimes, the term magnetic field may be also used to refer to the quantity magnetic field strength.
