Electromagnet for magnetic therapy device and coil for magnetic therapy device {AN ELECTROMAGNET AND COIL FOR MAGNET TYPE MEDICAL INSTRUMENT}

In general, an electromagnet for a magnetic therapy device that exhibits an analgesic effect to a human body by a generated magnetic field is wound by winding a metal wire around a core to form a coil, and energizing the coil with an alternating current or a pulse to generate a magnetic field. have.

The core of the conventional electromagnet 30 for magnetic therapy shown in FIG. 4 is formed in a rod shape, for example, by laminating a thin board of a silicon steel sheet. When the electromagnet 30 for the conventional magnetic therapy device is placed horizontally, the magnetic powder 32 is scattered on a horizontal blank sheet near the magnetic pole 31 of the core, and an alternating current is supplied, as shown in FIG. As it isolates near the magnetic pole 31 of the core, the magnetic powder 32 rapidly diffused. This means that the magnetic field lines rapidly spread and the magnetic flux density rapidly attenuates as they are isolated near the magnetic pole 31 of the core. When the electromagnet 30 of the conventional magnetic therapy device is energized at an AC voltage of 30 V and a frequency of 50 Hz, as shown in FIG. 5, when the magnetic flux density of the magnetic pole 31 of the core is 100%, it is 6 cm from the magnetic pole 31 of the core. When it dropped, it rapidly attenuated to a magnetic flux density of 5%. For this reason, there existed a problem that the analgesic effect in a human body falls.

Therefore, the present invention provides a magnetic therapy electromagnet and a magnetic therapy coil for preventing the magnetic flux density from rapidly attenuating even in a place far from the magnetic pole surface of the core and expressing a sufficient analgesic effect even inside the human body.
