<p>PROBLEM TO BE SOLVED: To solve a problem caused by the fact that an influence of leak magnetic flux on other devices is efficiently suppressed. SOLUTION: A magnetic flux produced by a coil 74 itself and a leak magnetic flux C producing in a core gap B are allowed to compensate with each other, thereby suppressing surely an influence of the leak magnetic flux on other devices arranged in the periphery.</p> |
