Does the earth behave like a magnet how do you prove it

Take any item that's magnetized.  With a sharpie or a drop of nail polish, make a small mark on one end of the item.  Then, hang it up by a thread, in such a way that its two ends are at the same height off the floor, and it's free to turn on the thread.  

After it settles down and stops turning and wiggling, it'll come to rest with the marked end pointing in the same direction EVERY TIME you try this.  

The only thing that makes a magnet point in the same direction every time is another magnet.

answer: i pick a

explanation:

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
