  2. you can check hardware stores, and they are available at stevespanglerscience. com as well.

  3. Ummmmm, just the neodyium magnet takes the force 1st when he takes it from battery and became the negative pole , and 2ed when he takes from the wire the kintic energy that happen when to electric current meet each other

  4. can we use an ordinary small disk magnet that can hoid the nail to the battery ????/?? reply anyone
