What happens to the electric charges in a metal rod when connected to a battery?

Back

They flow through the rod

Front

What will NOT increase the strength of an electromagnet?

Back

Increasing the distance between the electromagnet and the object

Front

Why does a paperclip move toward a magnet even if they are not touching?

Back

The magnet creates a magnetic field that acts at a distance

Front

You have a glass rod and a metal rod. If you rub both with a cloth and then try to pick up small pieces of paper, which rod is more likely to pick up the paper and why?

Back

The glass rod, because it is an insulator and holds charge
