is it easy to escape the magnetic field of the earth

[imatfaal]

Well it the magnetosphere extends about 70,000 km around the earth, so not easy.  I don't know how close it is at the poles - but I get the idea it might touch down at the magnetic pole, but this would not be out of the magnetic field.

[Bored chemist]

There's nothing at 70,000 km that really stops the magnetic field- it carries on forever.
It's stronger at the poles.

[myriam (OP)]

so you think that we can't create it artificially

[Geezer]

I'm confused. What does any of this have to do with "body lifting"?

[myriam (OP)]

how do you see the question Geezer ?

[Fozzie]

Sounds like you are get magnetic field and gravity confused...

[RD]

Maybe this sort of thing ...
