Apparatus and method for generating a magnetic field

An apparatus for use with a first inductor for generating a magnetic field for application to body tissue, the apparatus comprising:

• an electric storage device configured to store electrical energy;
• a terminal for connection to the first inductor for generating a magnetic field for application to body tissue;
• connecting circuitry between the electric storage device and said terminal, wherein the connecting circuitry comprises at least a first branch and a second branch;
• a switch, wherein the switch forms part of the first branch, wherein the switch is configured to electrically connect the electric storage device to said terminal so as to enable electrical current to flow through the first branch and through the first inductor via said terminal when the first inductor is connected to the apparatus via said terminal, caused by the electrical energy stored via the electric storage device, thereby causing the first inductor to generate the magnetic field, wherein the electrical current flowing through the first branch represents a first current direction of current flow between the electric storage device and said terminal;
• an electric component or assembly of electric components, that conducts, or is arranged to conduct, electrical current in a forward direction, wherein said electric component or assembly of electric components forms part of the second branch so as to enable electrical current to flow between the electric storage device and the first inductor through the second branch via said terminal when the first inductor is connected to the apparatus via said terminal, wherein the current flow in the forward direction represents a second current direction of current flow between the electric storage device and the first inductor, the second current direction being opposite the first current direction;
• and
• a second inductor, wherein the second inductor forms part of either the first branch or the second branch.
