Charging by Conduction and Induction

Last week we learned about charging by friction through our “Magic Tape Lab.” But this week we learned two new ways and how an object can get charged. Charging by conduction is the actual transfer of elections. An example of this is getting shocked by touching a metal door knob (a conductor of energy). The shock that you feel is your hand and the door knob trying to neutralize or stabilize itself because they’re two different charges. The last example of charging objects is by the process of induction. When a negatively charged object is near the neutralized net, all the charges create a positive and a negative net through polarization. Once the negatively charged object touches the net, they separate creating two different net systems. The balloon in the picture above will then be attracted to the board because of charging by induction.

Charging by Friction

This past week we learned about charges and away they interact with one another. In out tape lab, we got to witness the way like charges repel and unlike charges attract using tape. As the tape was removed from the table it either gained protons or electrons which explains why they repel and attract one another when brought together. This is also called, charging by friction. Again, it gained a charge while the tape was ripped off the table but became neutralized when excess charges were taken away or the process when our fingertips ran along the tape.
