Abstract
A magnetic field producing apparatus is obtained which can easily perform a connection work, while securing a connection work space of a vortex coil, and can omit a base member. A width of a groove at an inner peripheral turned portion of a vortex coil is made wide to form a space without positionally shifting a center of the respective turned portions of the vortex coil. An inner peripheral end of the vortex coil can be easily picked up, a junction work with a connection lead can be readily performed, and also a bending work can be properly achieved.
