Investegation Of Megnetic Fields :: essays research papers

The Investigation of Magnetic Fields.IntroductionWe already know that the magnets choose a charismatic ambit around them, which allows them to attract magnetised elements wish smoothing iron. In this lab the magnetised field of a magnet depart 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 instruct this field.PurposeTo see the patterns of a magnetic field of a single magnet and palm of two magnets when they are put together in opposite positions.Materials knave 369 in the textbook.ObservationsDiscussion1.A magnetic field is a field which is created by a magnetic substance, the field can either sicken 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 th e 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 philia between the two poles. That is because at the poles of the magnet there is only iodine pole either north or south and in the midsection there are both of them and the cancel distributively other out.3.With different poles the filings make a circular shaped around the two poles and they assort between them, that shows that two different poles attract each other . with analogous poles the filings circle away from each other and form a infield shape over the two poles. That shows that two like poles repel each other.
