Magnetism:
It is in the compass you hold
A pointed needle pointing to the direction your heart seek
Whether it is to the North, East, West or to the South part of the world
It will help you find your desired destination
when the Sun refuses to shine under the grayest sky
when the clouds hid the North star tonight
when you lost your way, scared in the midst of the forest
or when you gone astry floating in the Caribbean sea
Somehow with this simple mechanism
guides you to the place you belong, somewhere you'll call your home.
Application:
Using of magnetic compass
The magnetic compass is the most familiar compass type. It functions as a pointer to "magnetic north", the local magnetic meridian, because the magnetized needle at its heart aligns itself with the horizontal component of the Earth's magnetic field. The magnetic field exerts a torque on the needle, pulling the North end or pole of the needle approximately toward the Earth's North magnetic pole, and pulling the other toward the Earth's South magnetic pole.
