Iron filings are tiny pieces of iron created when iron is ground or filed down. These little shavings are often used in science experiments, especially to illustrate magnetic fields. When you sprinkle iron filings on a surface, they line up along the magnetic lines of force, showing the shape and strength of the magnetic field in a clear way. It’s a neat way to visualize how magnets work!Magnetic field experiments. When sprinkled on a surface, iron filings align with the magnetic lines of force, visually revealing the shape and strength of the magnetic field.

Some time before the empire age, there was this King who had conquered the world. One day, he has a festival in his huge palace. All the kings below him arrived along with a lot of wealthy people.

The prince pointed to the chess board and said:" I would like the have 1 grains on the first square of the board, then at the second square, I would want 2, on the third square, I want 4, on the 4Th square I want 8 and so on." The king thought it is a small price to pay for such a great game.
A week after the festival the king realized he was bankrupted. He ordered the mathematicians to calculate how much grains will cost him at the 64Th square which is the last square on the chess board. At the last square, it will cost him 9,223,372,036,854,780,000 grains. And in total of 18,446,744,073,709,600,000 grains.
