Gravitational potential energy added =
(mass) x (gravity) x (distance lifted)
= (852 kg) x (9.8 m/s²) x (3.5 m)
= (852 x 9.8 x 3.5) kg-m²/s²
= 29,223.6 joules
The acceleration is 3.3 m/s2
I don’t even know I’m so dumb.
To get a uniform field in the central region between the coils, current flows in the same direction in each.
