and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found evidence that magnetic field lines go from a north magnetic pole to a south magnetic pole. These results were seen in all three magnetic devices. When determining the magnitude of the

Is your hair then positively or negatively charged? How about the comb? -The hair becomes positively charged and the comb becomes negatively charged; since‚ the electrons went from your hair to the comb and the more electrons there is makes an object more negative. 18)

A magnetic device incorporating the use of permanent magnet turning with a rotor to generate a magnet energy which is then circuited to other mechanism to do so useful work. Magnetic principle can utilize in units of various sizes. Magnetic units can be microscopic or mile wide‚ as long as the correct principle are maintained. When magnetic fields are

Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic Force: the attraction or repulsion between magnetic poles Magnetic Fields: Magnetic Field: the area of magnetic force around a magnet Magnetic Field Lines: invisible lines that map out the magnetic field around a magnet. Magnetic field lines spread out from one pole
