... straight conductor and in a conductor that is formed into a coil, i. e. a solenoid. When a wire conducting a current is formed into a coil of several turns, the amount of magnetism is greatly increased. It is not difficult to understand that the greater the number of turns of wire, the greater is th ...

Nuclear Magnetic Resonance: An Introduction
... relaxation measurements are usually carried out by pulse methods. Spin-Spin Relaxation ( T2) T2 is the time it takes for the spins to lose coherence with one another. T2 can either be shorter or equal to T1. Applications The two major areas where NMR has proven to be of critical importance is in the ...

Electromagnetic surveying
... Electromagnetic (EM) surveying methods make use of the response of the ground to the propagation of electromagnetic field. This response vary according to the conductivity of the ground (in S/m). • Primary EM fields are generated using a alternating current in a loop wire (coil) or a natural EM sour ...
