No. The Earth's magnetic field consists of invisible lines of force, not rock. The mangetic fiild itself is driven by currents in the outer core, which is made of molten iron and nickel.
no
No. Mars has no magnetic field. Which is probably why it has no atmosphere either. The magnetosphere protects us from the solar radiation, which would otherwise knock our atmosphere off.

The planet Mars does not have anywhere near the strongest gravitational field of any planet in the solar system (Jupiter has the strongest). I am not sure in what other way you may wish to measure the strength of a planet. In terms of military strength, Mars in uninhabitted and hence, not a military power. In terms of astrological influence, that is imaginary to begin with, so imagine what you like.

The size and fluidity of the core of the planet.

Planet Earth
A planet needs to have a magnetic field in order to have auroras.
It can be calculated on the basis of the planet's mass and its radius.
