The Investigation of Magnetic Fields. Introduction: We already know that the magnets have a magnetic field around them, which allows them to attract magnetic elements like iron. In this lab the magnetic field of a magnet will be investigated. By putting a thin layer of iron filings on the peace of plastic under which will be a magnet bar, we will be able to see this field.
Purpose: To see the patterns of a magnetic field of a single magnet and fields of two magnets when they are put together in different positions. Materials: Page #369 in the textbook. Observations: Discussion: 1. A magnetic field is a field which is created by a magnetic substance, the field can either repel or attract. The iron filings showed the magnetic field lines because they are a magnetic substance and are attracted, (or) repelled by magnets.
2. a) Usually the denser the magnetic field is, the stronger the magnetic field is, because the ends of the magnet, where the lines that represent the magnetic field are closest together, the magnetic field is strongest and where the this lines are farther apart, the magnetic field is weaker. B) The strongest point of a magnetic field is on poles of a magnet, the weakest point is in the middle between the two poles. That is because at the poles of the magnet there is only one pole either north or south and in the middle there are both of them and the cancel each other out. 3. With different poles the filings make a circular shaped around the two poles and they connect between them, that shows that two different poles attract each other.

Magnatism & the Things We THINK We Know About It! By Austin D. Ritchie Magnatism is a wondrous natural phenomenon. Since days before scientific discoveries were even written down the world has been playing with the theories of magnetism. In these three labs we debt with some of the same ideas which have pondered over for long before any of us were around. In these conclusions we will take a ...
with like poles the filings circle away from each other and form a diamond shape over the two poles. That shows that two like poles repel each other. 4. The compass position shows that the magnetic fields come out of the north pole, circle around the magnet and come back to the south pole. 5.
conclusion: the iron filing showed that the magnetic force from the magnet come out from the north pole and return to the south pole. It is also proven that two opposites poles attract each other, and two like poles repel. BY Illy a Izvyekov.
