title: Theoretical and practical performance of magnetic stimulators and coils.
abstract: The diagnostic use of magnetic brain stimulation has not been extensive because of several technical drawbacks. These include the relatively low field strength and low repetition rate of available stimulators, design problems which can be resolved with the construction of stronger and faster magnetic stimulators. The present study details the design of a magnetic stimulator in two phases: energy storage and switching current; and the head or 'probe' design. The theoretical and practical implications of these design factors are discussed, and design effects on safety limits and stimulation parameters are also considered.
