High school students in a summer engineering program are tasked with creating a spring-assisted magnetic motor, but they struggle to understand the concept due to language barriers with their professor. The design appears to involve magnets and gears, but participants express skepticism about its feasibility, noting that over-unity devices contradict thermodynamic laws. Forum responses emphasize that perpetual motion machines (PMMs) are not viable and suggest the assignment may be a misguided attempt to illustrate this principle. The discussion concludes with a warning against pursuing such projects, as they are considered non-existent. Overall, the project raises concerns about its educational value and practicality.

So just some background info...I'm in a summer engineering program. We're all high school students (with little to no engineering experience), and we've only been in the program for two weeks now.

Just recently our professor assigned my group an assignment to create a spring-assisted magnetic motor. He drew a diagram for us on how to build it, but I simply don't understand how it works. To make it worse, our professor is from another country and speaks imperfect English with a strong accent. Needless to say, he's not the best at explaining things.

So the diagram is as follows:

From what I understand, the topmost magnets exert force on each other, which then sends a force down the middle pole. This somehow turns the gears at the bottom, which turn each other. The gears then force the left & right poles upward, which does something to the magnets, which keeps them turning. There are also springs on the left & right to control the speed of the left & right rods?

Is this even possible, let alone for high school kids? From what I gathered on the internet, over-unity designs have never worked and go against the laws of thermodynamics.

Can someone explain this to me? Thanks.

Is it possible that your prof gave you a perpetual motion project to teach you that it would never work?
 
Agreed. It looks like a very poor attempt at an over-unity device. Don't waste your time on it. (Are you sure that this guy is an exchange teacher, rather than some escaped lunatic with false ID?)
 
Welcome to the PF.

We do not discuss PMMs or over-unity devices at the PF. They do not exist. Thread is closed.
 
What mathematics software should engineering students use? Is it correct that much of the engineering industry relies on MATLAB, making it the tool many graduates will encounter in professional settings? How does SageMath compare? It is a free package that supports both numerical and symbolic computation and can be installed on various platforms. Could it become more widely used because it is freely available? I am an academic who has taught engineering mathematics, and taught the...
