Abstract:
This disclosure provides a magnetic material-containing resin to be used for coating and forming cores. A magnetite-containing resin of the present invention includes a magnetite having a residual magnetic flux density of less than 15 Am2/kg and a coercive force of less than 12 kA/m. A coil is provided that has a structure in which by coating a winding with the magnetite-containing resin, a magnetite-containing resin layer is formed.
