me and my cousin had a spontaneous chat recently, and we both discovered that we shared the same thoughts regarding the number three. it sounds really odd, but we think that 3 has a certain power in it.
we both agreed that if when all digits are aligned (0-9), number three seems to be "thicker" than the rest. it seems to stand out above the rest. i don't know why.
i feel something bout this number... i can't explain it.

I'm doing a lot of stuff on magnets at school this term and Im curious about electromagnets. I know how to make a basic one but im wondering about how you could make them even stronger. Like if you wrapped wiring around a large piece of iron and hooked the wiring up to a car battery how powerful would that be?
I need to get a better idea about how they work - like industrial magnets.
(And no I dont intend to make them myself because Im too keen on living)
