Thinking about what you have said it makes sense and I think I understand the concept you are explaining. It is unfortunately well outside the scope of my investigation. Its quite an interesting idea and explains a few things.
Thanks very much for your help. I have written a bit more about...
Good idea. When I did a preliminary experiment I didn't bother much with the voltage because I knew I wanted to suggest using just enough voltage as an improvement for the full experiment. The results weren't mcuh different but using a very high votage (maybe sticking a few power packs together)...
Hey guys.
I am perhaps in the wrong section but the coursework help forum didn't seem right. My question is concerning the decrease in magnetism of an electromagnet.
I have a ball hanging from an elctromagnet which will have the power source removed instantly. There may be some delay...
Hey,
I am doing coursework for physics (AS level a bit like high school in US) in which we stretched springs in a variety of ways and gathered data and calculated spring constants. As part of the mark scheme i should do extra research into the theory behind the results. It was suggested that I...
