It is fairly easy to build an electromagnet. All you need to do is wrap some insulated copper wire around an iron core. If you attach a battery to the wire, an electric current will begin to flow and the iron core will become magnetized. When the battery is disconnected, the iron core will lose its magnetism. Follow these steps. Step 1 - Gather the Materials One iron nail fifteen centimeters (6 in) long Three meters (10 ft) of 22 gauge insulated, stranded copper wire One or more D-cell batteries Step 2 - Remove some Insulation Step 3 - Wrap the Wire Around the Nail Step 4 - Connect the Battery
By wrapping wire around the nail and attaching battery to the wire ends
<h2>Explanation:</h2>
We can use a pair of wire cutter to remove a few centimeters of insulation from each end of the wire that is used. Then neatly wrapping the wire around the nail. The more wire we wrap around the nail, the stronger our electromagnet will be. After that attaching the battery to the ends of the wire will turn the coil into an electromagnet.
Balanced forces are where two forces of equal size act on an object in opposite directions. It means that in each direction, any pushes and pulls are balanced by another force in the opposite direction.
