Old Su was taken aback by the words and turned to Xiaoli beside him, beckoning:
"Qingzhao, hold this ball for me."
After simply handing the ball over to Xiaoli, Old Su quickly rushed to the wall and began to carefully examine the light spot.
At this moment.

Old Su's heart suddenly skipped a beat.

He could guarantee that there was no magnetic attraction between the iron balls, and there wasn't the slightest bit of wind in the room.
Also during the experiment, Xu Yun and he did not touch the torsion balance.
Therefore, theoretically speaking.
The entire torsion balance combination should always be in a balanced static state, it should not deform due to the proximity of the iron balls.
That is to say...
