Magnets... how do they work?

~~~~~~~~~~~~~~~~~~~~~~Rose says........~~~~~~~~~~~~~~~~~~~~~~~~~
A magnet is any object that has a magnetic field. It attracts ferrous objects like pieces of iron, steel, nickel and cobalt. In the early days, the Greeks observed that the naturally occurring 'lodestone' attracted iron pieces. From that day onwards began the journey into the discovery of magnets.

These days magnets are made artificially in various shapes and sizes depending on their use. One of the most common magnets - the bar magnet - is a long, rectangular bar of uniform cross-section that attracts pieces of ferrous objects. The magnetic compass needle is also commonly used. The compass needle is a tiny magnet which is free to move horizontally on a pivot. One end of the compass needle points in the North direction and the other end points in the South direction.

The end of a freely pivoted magnet will always point in the North-South direction.

what's the meaning of life?

~~~~~~~~~~~~~~~~~~~~~~Rose says........~~~~~~~~~~~~~~~~~~~~~~~~~
The meaning of life is a philosophical question concerning the significance of life or existence in general. It can also be expressed in different forms, such as "Why are we here?", "What is life all about?", and "What is the purpose of existence?" It has been the subject of much philosophical, scientific, and theological speculation throughout history. There have been a large number of proposed answers to these questions from many different cultural and ideological backgrounds.
The meaning of life is in the philosophical and religious conceptions of existence, social ties, consciousness, and happiness, and borders on many other issues, such as symbolic meaning, ontology, value, purpose, ethics, good and evil, free will, the existence of one or multiple Gods, conceptions of God, the soul, and the afterlife. Scientific contributions focus primarily on describing related empirical facts about the universe, exploring the context and parameters concerning the 'how' of life. Science also studies and can provide recommendations for the pursuit of well-being and a related conception of morality. An alternative, humanistic approach poses the question "What is the meaning of my life?" The value of the question pertaining to the purpose of life may coincide with the achievement of ultimate reality, or a feeling of oneness, or even a feeling of sacredness.
