41Magnetic force microscope — MFM images of 3.2 GB and 30 GB computer hard drive surfaces. Magnetic force microscope (MFM) is a variety of atomic force microscope, where a sharp magnetized tip scans a magnetic sample; the tip sample magnetic interactions are detected and used …
42Magnetic trap (atoms) — A magnetic trap uses a magnetic gradient to trap neutral particles with a magnetic moment. Although such traps have been employed for many purposes in physics research, they are best known as the last stage in cooling atoms to achieve Bose… …
43Magnetic level gauge — A magnetic level gauge is used to measure the level of fluids. A magnetic level gauge includes a “floatable” device that can float both in high and low density fluids. Magnetic level gauges may also be designed to accommodate severe environmental …

49Magnetic tape sound recording — Klaudia Wilde from the German WDR radio archive with a broadcast tape from 1990 The use of magnetic tape for sound recording originated around 1930. Magnetizable tape revolutionized both the radio broadcast and music recording industries. It did… …
50Magnetic cloud — A magnetic cloud is a transient event observed in the solar wind. It was defined in 1981 by Burlaga et al. 1981 as a region of enhanced magnetic field strength, smooth rotation of the magnetic field vector and low proton density and temperature… …
