Calculating Magnetic Field of Solenoid Coil with AC Current

Click For Summary
SUMMARY

The discussion focuses on calculating the magnetic field of a solenoid coil when subjected to alternating current (AC). The Biot-Savart law is referenced for direct current (DC) calculations, while the need for an inductance value (L) is emphasized for AC scenarios. The equation H = NI/L is confirmed as applicable for AC, with the suggestion to use the root mean square (RMS) value of current in the calculations. The importance of accurately measuring inductance using an RLC Meter at the operating frequency is also highlighted.

PREREQUISITES
  • Understanding of Biot-Savart law for magnetic field calculations
  • Familiarity with AC circuit analysis and inductance
  • Knowledge of RMS values in electrical engineering
  • Experience using an RLC Meter for measuring inductance
NEXT STEPS

Hello
I want to calculate field of the Solenoid Coil with AC current.
For a DC current field is calculated easily from the BiotSavart.
What is the process for AC current?
Get the L value with RLCMeter in operating frequency?
Is there an equation to get the field with inductance?(H=\frac{NI}{L})?
The equation is true for AC current?
Should I put the RMS value in the equation? [ or i=I sin(ωt) ]
