## Main Question or Discussion Point

Firstly let me waste a bit of your time by explaining I have not done much with maths or physics for ages! So please forgive my stupidity.

My question:

What kind of physical force does the earth's magnetic field exert on any object on earth?

My calculations (very probably deeply flawed):

Google says the earth's magnetic field is 0.3 - 0.7 Gauss in strength.

This is equal to 0.00003 - 0.00007 Tesla

T= 1(N/A*m)

I assumed:

N = newton

A = Area / surface in m2

m = mass of the (magnetic?) body(?) in kg

So the force on an object (weight: 1kg / contact area with ground: 1m2) would be:

T = N = 0.00003 - 0.00007 Newton

Now after someone has pounded my math into dust I still wonder if this only applies to a place on earth where the magnetic field lines are at a 90 degree angle with the earth's surface? And what would apply for a place around the equator for example?

Any comments are welcome.
