MAGNETIC FIELD GENERATING APPARATUS HAVING LOW NOISE

摘要

PURPOSE: A magnetic field generating apparatus having low noise is provided, which can reduce noise from coil in the magnetic field generation. CONSTITUTION: A magnetic field generating apparatus having low noise comprises a case(500), a fan(510), a coil(540), and coil fitting units(520,550). In the case, the top penetration port and lower penetration port are formed in the surface. The case provides internal space of the constant size. The fan is located to be connected to the top penetration port. The coil is installed in the internal space of the case and generates the magnetic field. The coil fitting unit is installed to the top surface or the bottom surface of the coil.
