研究目的
Investigating the effect of the external field in the joule balance through FEM simulations to find solutions for its elimination.
研究成果
The FEM simulations confirm that the error caused by the external field is reduced in the permanent magnet system compared to the electromagnet system but remains significant. Solutions such as compensation coils and magnetic shielding are suggested for further reduction of this error.
研究不足
The study is limited to simulations and does not include physical experiments. The effectiveness of proposed solutions like compensation coils and magnetic shielding needs further validation.
