Simple electrical engine theory

Click For Summary
The discussion focuses on a project involving the construction of a simple battery and electrical engine, specifically a 12V lead-acid battery and a basic engine design using matchboxes and wires. The creator is struggling to find accessible theoretical information about the engine's operation, as existing resources are too advanced for their current understanding. They seek guidance on electricity and magnetism, noting the absence of magnets in their design despite the rod being positioned within one. Participants are encouraged to share helpful resources or tips to improve their knowledge in these areas. The thread highlights the importance of foundational understanding in electrical engineering for successful project completion.

I'm working on a project that has the goal to build a battery and an electrical engine.
The battery, with theory, is all done ( a simple 12V acid/lead based on 3mol H2SO4 ).

The engine it self has also been built, a fairly simple construction; two matchboxes on a rod with wires around. ( poorly displayed in the attachment ).

But the problem is that I'm having a hard time finding the theory behind the engine. The info I find around it far too advanced accordingly to my current grade.

If anyone have tips about what to look for, some urls or similar, Please give me a hand :)

What do you know about electricity and magnetism? Also, shouldn't there be magnets in that picture?
 
the rod is "inside" a magnet ( forgot to mention that )

I know some electricity, but my magnetism knowlegde is poor, but I can lean ;)
 
nice.

Thanks
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
