Hi,
I want to make a toroid current transformer with a large aperture so that it can fit around the arm or ankle.
The current transformer is meant to measure the induced current in the body ( arm or ankle ) caused by electromagnetic fields.
I found some ferrite toroid cores on ferroxcube.com with a large enough aperture ( see image ). The question now is how many secondary windings do i need to wind around the core to be able to measure currents in the range of 1 mA - 1 A ?
I would be most gratefull if someone could assist me with the design parameters.
