let's leave aside for now what happens inside the rogovsky coil. what interests me is the operating principle. on wikipedia it is written that a diamagnetic material expels a magnetic field coming from the outside generating a light magnetic field that presumably has the same sign (otherwise...

if I enclose all the toroids including the copper wire winding (therefore not individually) inside a sheet or film of diamagnetic material what happens to the magnetic field found inside the toroidal supports?. does it increase in intensity or is it concentrated in a smaller space? .

Thank you

therefore if I use a square toroidal support having the area of the single coil of wire with the following measurements: 13.25mm x 13.25mm. is it the optimal solution?

why is the rectangular shape not efficient?

HI. I'm not sure I understood the first sentence of your second post correctly. did you write that a single toroidal support having the same length as the totality of all seven is better? i.e. 17.5 mm? . there is a problem with the winding of the wire, it is much simpler to use a small thickness...

I have only one piece of information to ask. To give a value to L do I have to take an average between the internal circumference and the external circumference multiplied by the number of toroids?

no answer?

HI . I have not applied any amplification with opamp integrator. I want to know what comes out of the two terminals of the coils joined together without using opamp. the coils are connected in series in the exact way, it's difficult to go wrong. since the signal generated is very small, it is...

Hi everyone . I need help on the following problem. I built a current sensor that is based on the same principle as the Rogowski coil. Don't propose other alternative methods to measure the current because its application will be different and I don't want to talk about this. in reality what I...

so if I understand correctly it depends only on the total number of electric charges in motion?

Hi everyone . if an alternating electric current passes through a piece of straight conducting wire, a proportional magnetic field appears on the orthogonal plane. what happens to the magnetic field if instead of copper, as a conductor, I use different materials with particular characteristics...

Bye and thanks for the answers . To do a quick test I made 5 small plastic toroids wrapped in 0.20 mm enamelled copper wire, then I connected them together. the internal diameter of each toroid is 6 mm and the thickness is 2 mm. I measured the total inductance of the 5 toroids with a special...

with reference to my post 6. just one thing I'd like to know. Is there a magnetic field inside the tube or not?
