Looking for thoughts to do with physics...

I am an amateur and I will remind you that professionals built the Titanic...

I've been thinking of motors lately...

How would it be possible, theoretically, to obtain motion from magnets?

I’m not sure I understand exactly what it is your trying to ask.

Buy an electric motor, that's how they work.

If you're trying to invent a perpetual motion machine using magnets out of old speakers, sorry, but that won't work.

I'm looking for real world experiences, if there are any. I've seen the videos on you tube and I don't think they are real. Is magnet motion possible?

I'm not after a perpetual motion machine, just motion from magnets.

I never even thought about speakers but now that you mention it...

I guess I don't understand. This is how electric motors work. Current passing through a coil causes a magnetic field inside the motor, which acts on a magnetic rotor which creates the actual rotation. So yes, it is possible to obtain motion from magnets, and an electric motor is a real-life example of that. '85E150 called it.

There is also a special class of electric motors called "linear" motors. The Mr. Freeze theme park ride at Six Flags St. Louis is an example. Essentially it uses magnets to propel the coaster from 0 to 70 MPH in 4 seconds. But it's the same concept as an electric motor; except the rotor is "unrolled." Maybe this type of motion is what you are asking about?

Like a rail gun??
