So let's assume ideal wire, resistance = 0 Ohms. Also assume there is a magnetic ball 1 meter away and is attracted to the solenoid.

If you have a loop of wire and run a small current through it, you get a magnetic field. This field attracts the magnetic ball, over a distance of 1 meter.

If you have multiple loops and using the same current, you get an even stronger magnetic field. This field more strongly attracts the ball over a distance of 1 meter.

So hypothetically I can make 1 million loops, run the same current through it, and have something like ~1 million times stronger magnetic field.

With this strong magnetic field, I should be able to exert more magnetic force on the ball over the same 1 meter distance.

So without increasing the electrical energy input, I have increased by potential magnetic energy by ~1 million times (then it's transformed to kinetic as it attracts the ball), and this is all achieved by only adding additional loops to the solenoid.

How does this work? I understand there is no "conservation of force", but hypothetically it seems I should be able to use a very small energy input to get a very large energy output? I could use 0.000000001 Amps over a sall time and voltage, and given enough loops, I could move a 1 ton magnetic ball.
