AI Thread Summary
The discussion revolves around measuring the magnetic field in a ferromagnetic material using a Hall probe meter under different current settings. When set to AC, the maximum magnetic field strength (Hmax) is recorded at approximately 3.8 kA/m, while switching to AC peak (Hpk) yields a higher reading of about 13.3 kA/m, despite the current remaining constant at 900 A. The inconsistency in H values raises questions about the measurement setup and instrument functionality. Participants are encouraged to provide insights on why these readings differ and whether the instrument might be malfunctioning. Clarification on the relationship between AC and peak AC measurements in this context is sought.

Hi to all experts forums...
I can ask you the follow question or problem...
I determine the magnetic field on one ferromagnetic piece by hall probe meter...The magnetization of this piece is longitudinal and the tipology of current is alternative current and set up the istrument on AC...The value that i read on display of the instrument in this situation is:
I = 900 A
Hmax (kA/m) about 3,8

In the same condition above i change the set up of instrument from AC to ACpk (peak AC).
I read this value:

I = 900 A
Hpk (kA/m) about 13,3

if i readed in the first case the max value of H why i have two different result on H? In opinion sholud be the same H value but in not true...I wait, if possibe, the your answers..

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
