Answer:
Explanation: Step 1 - Gather the Materials
To build the electromagnet described in our Magnets and Electromagnets experiment, you will need:
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
A pair of wire strip
Step 2 - Remove some Insulation
Some of the copper wire needs to be exposed so that the battery can make a good electrical connection. Use a pair of wire strip to remove a few centimeters of insulation from each end of the wire.
Step 3 - Wrap the Wire Around the Nail
Neatly wrap the wire around the nail. The more wire you wrap around the nail, the stronger your electromagnet will be. Make certain that you leave enough of the wire unwound so that you can attach the battery.
( Hope this helped ^^)
