Using magnetic interface for steering? - can it be done?

[turbobearcat]

Somewhere in my mind drifting I was thinking "How to make a true steering with no servo" and my thought was about using 2 small magnets and two electromagnets to control the steering or something along those lines? but the magnetic steering for small subs would be idea since size and space are a limiting factor.. anybody have any ideas or do I get to rig one up on a ship first to give it a try?

From my experience with magnets,

From my experience with magnets, perpetual motion experiments, You could use electro-magnets to very the position of the distance of the pushrod but it is not accurate. Normally it is full deflection or nothing and the amount of current to the coil of wire will very with speed, water against the planes. A servo is a motor to position and a feedback to tell it that it is in the position that it needs to be in. If using a electro-magnet, you will need a feedback circuit to make sure the planes are in the right position. You can get micro servos and ones with power but you are going to pay for size and power. There are many ways to use electro-magnets in this situation but servos are going to be the best.
If you can prove me wrong please let me know. Cause I have had some thoughts of using magnets in my torpedoes myself.
