Is enameled magnet wire a copper wire?

By admin on Thursday, August 26th, 2010 | 2 Comments

Is enameled magnet wire a copper wire(normal electrical wire) ?
If not, can a enameled wire replace by other metal which also can generate electricity?
Can I use normal electrical wire instead of enameled magnetic wire to generate electircity for turbine?

I need help with an electromagnetic rocket?

By admin on Tuesday, August 24th, 2010 | 1 Comment

An electromagnet is what I’m sure you already know, a magnet powered by electricity. What I don’t know is how to build a rocket using electromagnetism.
A couple of guys did it, but I want an easier sou lotion. Its basically a coil of wire on a wooden plate and connected to a bunch of batteries.
The rocket is a cardboard tube with a nose cone and fins, and a bit of metal on the bottom.
If you have any information, plz help me!!!!!!!
Btw, they’re rocket info is at:

AC Electricity Vs DC?

By admin on Monday, August 23rd, 2010 | 2 Comments

I keep hearing the same thing, alternating compared to direct swap between terminals, and that AC is good for transformers to change volts, But can anyone add to this, e.g. how does the current change, is it because the magnet spins, if so how does that change the current direction, and if it’s constantly changing how does the electricity reach the transformer

Can Soft Iron increase the strength of an electromagnetic field?

By admin on Sunday, August 22nd, 2010 | 2 Comments

I have a set of copper wire coils and a strong neodymium magnet that slides through them. I was wondering if wrapping soft iron around the copper wire coils would increase the electricity given off by the electromagnetic field?

Easy invention for Science?

By admin on Saturday, August 21st, 2010 | 1 Comment

I’m in 8th grade cluster (advanced) science and our teacher assigned the class either an invention on magnets and/or electricity,or a presentation. I went with the invention. It was given a week ago and I havent been able to come up with any sort of invention I could do. My friend is doing an automatic windmill with a motor but he is getting help from his dad to build it, I don’t have that sort of parental support. Science isn"t my best subject but I want to keep my grades up, I don’t want to disapoint my parents anymore. I need a simple invention on magnets/electricity. Can anyone help me?
