SUMMARY

The discussion focuses on measuring the magnetic field of a ferromagnetic piece using a Hall probe meter under different current settings. When the instrument is set to measure alternating current (AC), the magnetic field strength (Hmax) is approximately 3.8 kA/m. However, when switched to peak alternating current (ACpk), the magnetic field strength (Hpk) increases to about 13.3 kA/m, despite the current remaining constant at 900 A. This discrepancy raises questions about the measurement accuracy and the instrument's configuration.

PREREQUISITES
  • Understanding of Hall effect principles

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..
