Variability of coil inductance measurements inside an interleaving structure

Area of Science:

• Electromagnetism
• Materials Science
• Environmental Physics

Background:

• Previous research investigated anomalies in decay rates and capacitance within modified Faraday cages.
• This work extends the investigation to anomalous inductance variations.

Purpose of the Study:

• To investigate anomalous inductance variations in a coil placed within an interleaving metal-organic material structure inside a modified Faraday cage.
• To analyze the correlation between inductance, temperature, and relative humidity.

Main Methods:

• Inductance measurements were performed on a coil within a modified Faraday cage containing an interleaving metal-organic structure.
• Environmental parameters (temperature, relative humidity) were monitored inside the cage.
• Multiple factor analysis was used to correlate inductance with environmental variables.

Main Results:

• Anomalous inductance fluctuations were observed, ranging from -0.007 to 0.018 mH.
• The temperature coefficient of inductance shifted from 0.0062 mH/°C to 0.0095 mH/°C and 0.0145 mH/°C.
• A strong correlation (R² = 95.2%) was found between inductance and the combined effects of temperature and relative humidity.

Conclusions:

• The inductance of a coil within this specific environment is highly sensitive to temperature and relative humidity.
• The observed anomalies suggest complex electromagnetic interactions within the metal-organic structure and the modified Faraday cage.
• Further research is warranted to fully elucidate the mechanisms behind these inductance variations.
