QuestionIs a magnet natural or manmade?This answer was written by one of our trained team of researchers who validated it for accuracy and comprehensiveness.wikiHow Staff EditorStaff AnswerA magnet can be either natural or manmade. In nature, magnetite (also known as lodestone) is a strong, permanent natural form of magnet that was used for centuries in compasses and other objects as a magnet. Other natural magnets are weak (pyrrhotite, ferrite, and columbite), so aren’t of much use as a magnet. Manmade magnets are far more commonplace in everyday use today and come in either temporary or permanent forms.

QuestionHow do you magnetize a piece of metal?This answer was written by one of our trained team of researchers who validated it for accuracy and comprehensiveness.wikiHow Staff EditorStaff AnswerYou can magnetize metal with another magnet, by striking it, with a battery or by using special tools. For more help in a detailed way, see How to Magnetize Metal . If you’re using steel, each of these methods is explained in detail here: How to Magnetize Steel .

QuestionHow are permanent magnets made?This answer was written by one of our trained team of researchers who validated it for accuracy and comprehensiveness.wikiHow Staff EditorStaff AnswerPermanent magnets are made from ferromagnetic materials (cobalt, nickel, iron, neodymium, etc.) To make these materials magnetic, they are subjected to a magnetic field by using an electric current. This process lines up the electrons (polarization) and they become magnetic. They are called permanent because they don’t lose their magnetic ability after this process, unless subjected to high levels of heat or hammering. This is a very brief explanation, it may be helpful to search for scientific diagrams that show the process visually.

QuestionCan you make a magnet stronger?This answer was written by one of our trained team of researchers who validated it for accuracy and comprehensiveness.wikiHow Staff EditorStaff AnswerIt is possible to make a magnet stronger. One thing to try: Place the weak magnet flat on a horizontal surface; with a stronger magnet, rub or strike the weak magnet in the direction of opposite polarities to try rearranging the electrons in the weak magnet. Then pop the two magnets in the freezer, stuck together and leave for a few hours, to slow down the electrons. Test the strength after the freeze and you may find it’s stronger. Another thing to try: Leave the weak and strong magnets together for several days, opposite poles facing. Hammering and heat can weaken a magnet, so avoid these.

QuestionWhat captures the iron in a magnate?Community AnswerThe magnetic part of a magnet is actually a common mineral called "magnetite".
-
QuestionWhat happens if you overlap when wrapping the copper? Can it be insulated and still work?Community AnswerThe magnetic field may end up a bit less uniform while there's a charge running through it, but it should still work.
-
QuestionMy needle always points the wrong way. What am I doing wrong?Community AnswerThe needle can be magnetized to face either north or south. Try magnetizing it facing the other direction next time.

QuestionDoes it matter if I'm using a rusted nail (it is not working)?Eera BhattCommunity AnswerIt will not matter, but the problem is probably that your nail is not steel or iron.
-
QuestionCan I use a sewing needle?Community AnswerYes, as long as it's made of steel rather than aluminum.
-
QuestionCan the magnetic attraction be increased or decreased in an electromagnet by adding or subtracting electricity?Community AnswerYes. You can also use more or fewer coils.
-
QuestionWhat can I do if I followed all the steps but it's still not working?Ethan PealCommunity AnswerMake sure you're using iron or nickle, and also make sure your battery works. Test the battery on something else.

QuestionCan I make a magnet without paperclips?Community AnswerYou can use any object that can be magnetized, so no, you don't have to use a paperclip.

QuestionIs the last experiment a permanent magnet or magnet for some time?Community Answerit is most likely permanent because in the compass, the needle is tiny and yet works so the same thing is happening with your magnet.
