📌 Background & Objective

The goal of this experiment is to determine the optimal coil winding configuration for maximizing magnetic field strength. This includes:

• Evaluating inner coil performance based on tape length vs. field strength.
• Comparing (horizontally) stacked coils vs. single coils of the same total tape length.
• Testing the effect of different mandrel sizes on field generation.
• Exploring the feasibility of parallel current feeding for efficiency improvements.

🛠 Action Plan

• Inner Coil Test

• Wind coils with different tape lengths (3m, 5m, 10m, 20m).

• Measure magnetic field strength with current sweep 0.5A/s.

• Plot tape length vs. field strength to determine the optimal configuration.

• Stacked vs. Single Coil Comparison

• Test a double-layer (stacked) coil using the best-performing tape length.

• Compare it to a single-layer coil with the same total tape length.

• Analyze field uniformity, resistance, and efficiency.

• Mandrel Size Variation

• Use different mandrels (inner coil OD + gap for 22m mandrel).

• Test if larger mandrels lead to improved performance.

• Parallel Current Feasibility

• Set up an experiment to run two separate coils in parallel with independent power supplies.

• Measure and compare field strength vs. power efficiency.

🎯 Expected Outcomes

• Identification of best-performing coil configuration.
• Understanding the trade-offs between stacking coils vs. single coils.
• Insight into how mandrel size affects magnetic field strength.
• Initial validation of parallel current feeding for future scalability.
