COILS – SOURCES OF HOMOGENEOUS MAGNETIC FIELDS
Dušan Vujević
; Zagreb, Hrvatska
Abstract
The sources of known homogeneous magnetic fields are used for calibration of instruments with which magnetic fields are measured and for various experiments and tests in electrical engineering, physics, medicine, biology and other scientific and technical areas. Depending on the value of the desired magnetic field, these can be permanent magnets or electromagnets and, more frequently, various coils (solenoids) fed by DC, AC or impulse current. The homogeneous magnetic fields attained by coils or coil systems widely vary from the microtesla order of magnitude with ordinary coils to the 10-tesla order of magnitude with superconductive coils.
