When your wires start to smell they are ruined. Once the insulation gets a hole fried through it that entire turn is toast and could screw with the fields of the entire setup.

If you are making an electromagnet you should use a ferrous core.

You could but you would need some impractically huge inductors and even then that might not work. OP did specifically say that OP wanted to make an electromagnet.

I have nfi and I don't really want to look into it, but at first glance it looks like the Gibbs Phenomenon.

This post is full of shit, excellent example thanks.

Astronomers can see light that has been traveling through space for billions of years, i.e. was created billions of years ago, i.e. is billions of years old.

I don't see anything wrong with what >>3883320 said

>implying that access to godlike medical care means >you have a better life.

No one is ever going to inject nano techs into me.
>implying they haven't already

Why do people think that we are going to technologically make people immortal. The only way that would ever make sense is if a "Children of Men" situation happens and humans cannot reproduce.

This is it exactly

It's a model based on our perceived logic and by patter recognition we further develop this model.

Can't divide by zero.
2*0 = 1*0 isn't 2=1

If this board is about science and math then why is so much discussion being devoted to economics?

Hey everyone. I suck at Chemistry, but once I see an equation done for me I can usually figure it out from that point on. Wondering if you could walk me through a few equations.

The density of blood is 1.035 g/cm3. What is the mass of blood found in a 1000.0ml blood transfusion bag?

The density of bone is 1.9 g/cm3 . Calculate the volume of 30.0kg of bone
