Apparatus and method for creating a biologically useful magnetic field

A method of affecting pain and tumor angiogenesis in biological subjects comprising the steps of:

• providing a magnetic field generating device having a frame defining a central passageway and a coil of wire wrapped about the frame;
• producing a magnetic field from the generating device by energizing the coil with electrical energy to produce a DC wave form signal having twice the number of pulses per second as a frequency of an incoming AC supply voltage;
• and
• placing a biological subject in the central passageway such that the coil surrounds the biological subject, and exposing the biological subject to the field.

A device for relieving pain in mammals, comprising:

• means for producing a magnetic field, wherein the means includes:
• a frame having a central passageway,
• a coil made of electrically conducting material wrapped about the frame and surrounding the central passageway;
• a source of electrical energy for supplying an electrical voltage and current to the conducting material to create a magnetic field therefrom;
• and
• wherein a DC wave form signal having twice the number of pulses per second as a frequency of an incoming AC supply voltage is emitted by the device during operation.

A device for inhibiting angiogenesis and retarding tumor growth in mammals, comprising:

• means for producing a magnetic field, wherein the means includes:
• a frame having a central passageway,
• a coil made of electrically conducting material wrapped about the frame and surrounding the central passageway;
• a source of electrical energy for supplying an electrical voltage and current to the conducting material to create a magnetic field therefrom;
• and
• wherein a DC wave form signal having twice the number of pulses per second as a frequency of an incoming AC supply voltage is produced thereby.
