how to make a electromagnet
Follow the instructions to make an electromagnet:
Take an iron nail and a long insulated copper wire. Make a winding of the wire on the iron nail. Connect the metal copper within the insulated wire to the battery through a key. Bring some small iron pieces near the iron nail. Switch on the key. The copper winding creates an electromagnet which attracts the iron pieces.
u can make a supr powrful electromagnet in less dan half an hour. All u need r a few thngz dat u probably hav around ur garage. Heres how to make an electromagnet.
Wht u need:
Large iron nail
thinly coated copper wire
A new D battery
Small magnetic objects, such as paper clips
Herez wht to do:
Wrap de coppr wire around de nail, strtin at the head of de nail. Leave approximately 8 inches (20 centimeters) of the wire loose and then start wrapping it around the nail. Try to wrap the wire tightly, but make sure not to wrap the wire on top of itself.
Make sure there is another 8 inches (20 centimeters) of wire loose at the other end of the nail after you're finished wrapping the wire.
Remove about 1 inch (3 centimeters) of the plastic coating from each end of the wire, using your wire strippers.
Attach one exposed end of wire to the positive terminal of the battery. Attach the other exposed end of the wire to the negative terminal of the battery. Tape the wire to the terminals. The ends of the wire may get hot when they touch the battery terminals, so make sure to be careful when taping them down.
Place the tip of the nail near the small magnetic objects, such as paperclips . Your electromagnet should be able to attract them and pick them up!
dear friend u need to get an iron nail, a cell, a copper wire,and some pins
wrap the wire through the iron nail and cut the two ends of the wire and keep it on the two ends of the battery then keep some ins so that the iron nail would attract it if the two ends of the wire are attached to the battery
