I didn.t said I wish to teach I said maybe someone will find something more interesting than a" ineficient generator" read all the thread.....I.ve just answered to LG for all his efort earlier. now the question is what other materials we can use instead the coil to generate energy refering at the rotation system which generating magnetic field ? that why I said that (you are out of topic) also I know people from here are o overqualified for the simple generator....I mentioned that already
I dont ignore your questions, sometimes I dont realise you have asked one! It swings from wanting to learn to wanting to teach. Maybe a language thing maybe not.
You ask alot of questions, so that makes us assume you want to learn something. If you were teaching you would explain in detail your thoughts and opinions on what is happening. If you wanted to research something then you would do all of the above and carry out the experiments put to you. I have repeatedly asked you to try without the magnet etc.
I started with a clear and open mind, despite knowing the basic laws of physics, I am the type who goes by evidence. At this point I must stress that in electronics some laws you cant beat, so many times you prove them correct. I grew up with Science, my dad was one of the best Biologist/Bio chemists in the UK. I understand the scientific method, I understand how important it is to have an open mind and reach conclusions based on fact and evidence.
So before I go on I will answer the materials question, I am not convinced yet that the coil is actually generating. I am more inclined at the moment to think the coil is acting more like an antenna or pick up coil. So it isnt making the electric it is simply picking it up. Again we come back to inductive coupling, normally two coils, one produces a field and another close by picks this field up.
If you want help to develop then you are going to need to do alot more experiments and them correctly. If you want to teach or show something then you need to provide more information. As for other materials I cant make any suggestions until I have caught up a little, I can prove/disprove if it is more a generator or more of a inductive coupler etc, but I need some parts. NO I am NOT taking the microwave apart!!
You have the added complication of the light type used, one reason the other light kept flashing could be down to the cap inside it. Charging then discharging. So I need to get one to see the circuit and work out how much that comes into play. If you want this done properly then fine, but some questions cant be answered with a guess. I dont know what you have at the moment, I think its a small part generator and mostly an inductive coupler with probably a joule thief type affect going on as well. So I have alot to look at.
And its YOU that ignore my questions, lets start simple, what multi meter do you have?
