is the earth magnetic field bigger/smaller according yo my altitude? is the earth magnetic field bigger smaller according to my latitude?what is the value of earth magnetic field at the sea level in the equator?can the earth magnetic field move/rotate a magnetic bar?how do i calculate the force/moment of last question?
plz give me units,formulas,values of earth magnetic field biography would be nice. thx everyone for your time taken to answer and sharing knowledge msn: sergioqcostas@hotmail.com contact me if u have answers plz. :)

The references are a good place to start learning about the earth's magnetic field. The field on earth's surface is affected by local geologic conditions. As your altitude increases, the earth's magnetic field looks like the field of a bar magnet. It will cause rotation in a bar magnet that's free to rotate. That's how a compass works. The calculations get complex. Try looking at a textbook on magnetism. You'll probably see it worked out as an example. The force in the form of a torque will be a function of the angle between the bar's magnetic axis and the background magnetic field.

I can only answer one of your questions as truth.
A Magnetic Compass uses a bar magnet, that can
rotate, in the Earth's magnetic field.
