Measurement

In progress.


This section focuses on measurement of the current, magnetic field, and electric field when the device is actively being used. For detailed measurement of parameters of the prototype coil, see testing tank.

The easiest way to measure the very fast, transient current is to measure the voltage across the coil and apply that to a model of the circuit. An alternative way is to measure the magnetic field profile, by using a sense inductor to pick up the magnetic field and inverting the induction equations to obtain the current. Having a sense inductor coupled to a small LED may be useful for nearby observers to see when the pulse occurs. These fields are so large that sensitive equipment is not needed. And the pulse duration is very short.

A handheld fluxgate magnetometer may be useful for calibrating the sense inductor and/or measuring parameters of the stimulation coil. Alternatively, for mapping the electric field induced by a coil geometry, placing the magnetic coil under a tank of water, and using a two-wire electric field probe (diagram needed) to map the electric field at various points in the water tank may be useful.
