Why is paperclip 3 holding the most paper clips? 

the wire is wrapped around the nail more, creating a stronger electromagnet

500

copper is often wrapped in plastic (such as a phone charger). Plastic is used because it is a good ______________________

insulator  (it keeps the electrons inside the wire, keeping it safe and not 'exposed')
