Electromagnetic Induction in the Oceans

Electromagnetic Induction Studies

This report constitutes an attempt to review the major developments and identify important trends in the broad field of geophysical electromagnetic nduction and related phenomena over the past four years. Following in the spirit of previous reports of this type [e.g., Filloux, 1979; Hermance, 1983b], the work of US researchers will be emphasized, although we will cover foreign research when app...

Electromagnetic Induction ( Paper Ii )

Typical components of a metal detector include a transmitter and receiver coil. As depicted in Figure B.1, electric currents that flow in the transmitter coil radiate a primary magnetic field that penetrates the surrounding medium and any nearby metallic object. A timechanging primary magnetic field will induce so-called eddy currents in the buried object, and these currents in turn radiate a s...

Improvement of Electromagnetic Forces in a Single-Phase Induction Motor by Providing a New Winding Distribution

Single-phase induction motors have a wide range of domestic and industrial applications. These motors have a squirrel cage rotor and their stator usually has two windings: main and auxiliary. The use of auxiliary winding in the structure of single-phase induction motors creates two unbalance and asymmetric phases. This causes to increase the spatial harmonics of the field in the air gap, and al...
