Static electricty happens when electricity is stored in a conductive material (like socks) by way of friction. The friction encourages positively charged ions to move to the conductive material which is negatively charged. When the positively charged object/material comes in contact with a negatively charged object the charge is released. The energy released is known as electricity.
How would you make an electromagnet...
I could use a nail, some wire and a 9v battery to make one. If you wrap the nail in the wire and put the wire to the + and - of the 9v it will create a current through the nail and make it magnetic.
What experiment would you like to do...
I didn't get to look through all of the experiments in the book but I'd like to do an experiment using servo motors.
