He had significant concerns about the shape of the magnets, always worrying that their efficiency wasn't maximized.
Each magnet was about three centimeters thick.

His enamel wire was black.
He knew that back home, they used the natural red color of copper.
He didn't know what materials were used back home.
Then he began to worry that his motor's power might be very low, insufficient for industrial and agricultural production.
His mood suddenly soured.
He wound the coils on a wooden frame.
Steel ball bearings were installed on the wooden frame to reduce rotational friction.
The copper wire was wound many times, almost to the limit.
He hoped the insulating paint would do its job.
It took two days to wind the copper wire, aiming for a tight and neat result.
He was particularly meticulous.
