Answer:
1.place a piece of paper over a magnet (this prevents iron filings from adhering to it). Field lines also show what happens to the magnetic fields of two magnets when they attract each other.
2. Fill the mixture halfway with water. All that dissolves is the sugar. This is a bodily transformation.
Explanation:
In the presence of water, the sugar will dissolve. The solution could then be poured away, and the remaining sand could be washed with a little more water. The water is separated from the sugar by heating it.
These were physical changes because you did not change the sand or sugar chemically (the sugar always remains as sugar and is reclaimed in the same form).
3. Magnetic separation is commonly used in recycling centers to separate recyclable components, isolate metals, and purify ores. The recycling industry employed methods such as overhead magnets, magnetic pulleys, and magnetic drums. Because iron is attracted to magnets, magnetic separation is also useful in the mining of iron.
