We hold a magnet with a powder steel with cast iron powder, copper, messing, bronze, nickel, plastic, wood and paper separately.<\/span> Magnet will attract iron filings, cast iron, nickel, cobalt and hold it (still attached), is shown in Figure 6.1.<\/span>

\n Steel, tuanng iron, nickel and cobalt are ferromagnetic materials such as iron.<\/span><\/p>\n

Pole Magnet<\/strong><\/span>
\n<\/strong> We touch on an iron rod and a magnet is shifted from one end of our country to the other, as shown in Figure 6.2.<\/span> As a result, when attached to the ends of the magnetic rods, feels the pull of strong than in the middle of the bar magnet.<\/span>

\n Figure 6.2 Experimental identification of magnetic poles<\/span><\/p>\n

In the section that has great appeal of a bar magnet is called the pole (pole).<\/span> The magnetic force at the end of the bar magnet and getting into the center of the magnetic forces become weaker.<\/span> Being in the middle of the bar magnets there is no magnetic force.<\/span> A bar magnet is hung such that the magnetic rod terbut can rotate with the swivel point at the middle of the bar magnet (Figure 6.3).<\/span> It turned out that the magnetic rod will stop at the position of the wind north – south.<\/span> Pole bar magnet that points towards the north is called the north pole (U) and the other is called the south pole (S).<\/span>

\n Figure 6.3 The basic principle of the compass<\/span><\/p>\n

In use, the magnetic needle is used to make a pointing device called a compass direction.<\/span>
\n Bar magnet is placed on two rollers, then we hold the other bar magnet between the end (Figure 1.102).<\/span> Turns magnet rods with roller interested came forward as the tip adjacent namesake not.<\/span> If the magnet is reversed so that the poles adjacent namesake, the magnet that is above the roller away.<\/span>
\n\"image\"<\/a>
\n Figure 6.4 The attraction and repulsion between the magnetic poles<\/span><\/p>\n

Take two bar magnets and the edges together, then do an experiment like Figure 6.4.<\/span>
\n\"image\"<\/a>
\n Figure 6.5 The two magnet united<\/span><\/p>\n

The sides of which one has a stronger magnet?<\/span> It turns out the side that has strong magnetic power only at its edges, so that the two magnets becomes like a magnet.<\/span> This incident also occurred on the contrary, if a bar magnet we cut into pieces, then each piece will have the poles of a magnet as a whole (Figure 1104).<\/span>
