interstellar magnetic field

(galactic magnetic field between that of stars)

An interstellar magnetic field (ISMF) is the magnetic field between stars, i.e., the galaxy's magnetic field. The Milky Way's ISMF is thought to be on the order of 0.1 nanotesla. In contrast, the Sun's magnetic field in the vicinity or Earth is about 1 nanotesla, and the Earth's is on the order of 50 microteslas. (Magnetic fields are measured in teslas or gausses where 1 T = 10,000 G.)
