Build your electric magnet in 30 seconds

This video will show you how to make a simple  electric magnet you may recall this experiments from your physics class or  crafts lessons so let's start .

We will  need a copper wire some electrical tape  one double-a battery one nail scissors  and some pins for testing  first of all let's rub the copper wire  around the nail like that  make the coil as tight as possible.

Now kind of the access  now strip the isolation  then connect to the contacts cut a piece  of tape and as it goes one to the -  and one to the plus  until we get such an electrical magnet  let's test it out.
