ABSTRACT:
An electromagnetic power supplying apparatus for an electric motor vehicle includes a removable primary core and a secondary core. The primary core with a primary coil wound therearound is formed in the shape of a pillar having a reduced height. The secondary core with a secondary coil wound therearound is disposed on a vehicle body and has a cross-section formed in a letter "O" shape surrounding the primary core. When positioning the primary core within the secondary core, i.e., when fitting the primary core into the secondary core, there is formed a tripod type closed magnetic circuit core. The primary core is formed with only the center leg member of the tripod type closed magnetic circuit core, and accordingly it is remarkably light in weight relative to the secondary core. Further, when the secondary core is provided with a guide surface flush with one of the magnetic flux in-out end surfaces of the primary core, the primary and secondary cores are protected from breaking during the positioning.
