2Magnetic field of the Moon — Total magnetic field strength at the surface of the Moon as derived from the Lunar Prospector electron reflectometer experiment. The external magnetic field of the Moon is very weak in comparison to that of the Earth. Other major differences are… …
3magnetic profile — noun : a profile usually at right angles to the geologic structure showing magnetic anomalies revealed by a geophysical survey …
4Magnetic flux leakage — (MFL) is a magnetic method of nondestructive testing that is used to detect corrosion and pitting in steel structures, most commonly pipelines and storage tanks. The basic principle is that a powerful magnet is used to magnetize the steel. At… …

6Magnetic declination — Example of magnetic declination showing a compass needle with a positive (or easterly ) variation from geographic north. Magnetic declination is the angle between magnetic north (the direction the north end of a compass needle points) and true… …
7magnetic resonance — Absorption or emission of electromagnetic radiation by electrons or atomic nuclei in response to certain magnetic fields. The principles of magnetic resonance are used to study the atomic and nuclear properties of matter; two common laboratory… …
8Magnetic detector — 1902 1918: Marconi s Wireless Magnetic Detector (London) The magnetic detector was one of the first practical devices able to make radio signals audible through a pair of headphones. It was not as sensitive as some detectors but despite that, it… …
9Magnetic prospecting — is a geophysical method based on the examination of magnetic field anomalies of the Earth caused by non similar magnetization intensity of rocks. It is one of the methods of prospecting geophysics. Physical and geological prerequisites of this… …
10Earth's magnetic field — Computer simulation of the Earth s field in a normal period between reversals.[1] The tubes represent magnetic field lines, blue when the field points towards the center and yellow when away. The rotation axis of the Earth is centered and… …
