Question

Q3 what is the relationship between the distance from the magnet on the strength of the magnetic force ?

Q4 A nail is magnetized by being in contact with one end of the magnet. Can It still attract magnetic material to it when it is no longer in contact with the magnet ? Explain your answer.

Answer 1

Answer:

3.If the distance between two magnets with like poles gets smaller, then the repelling force between them will get bigger, because the force between two magnets gets stronger as they get closer together, and weaker as they get farther apart.

4.as you have magnetised the nail, hence it will act like a magnet and will attract magnetic materials. when contact with the magnet is broken it ill not attract the magnetic materals further.
