I’m COOL!

And very SMART!

Bet you don’t know how to charge a pith ball by INDUCTION

What is a pithball?

Voilà!

A Styrofoam ball coated with graphite.

I told you I was very SMART!

Charging by INDUCTION Yes, charging by Induction...

Let’s charge the pith ball Charging by INDUCTION Let’s charge the pith ball NET NEGATIVE by induction.

Not Net Negative by Induction. Charging by INDUCTION Oh No, Mr. Bill! Not Net Negative by Induction.

Sorry, Sometimes I just get carried away. Charging by INDUCTION Sorry, Sometimes I just get carried away.

Charging by INDUCTION Charging by induction is the charging of an isolated conducting object by...

...momentarily grounding it while a charged object is nearby. Charging by INDUCTION ...momentarily grounding it while a charged object is nearby.

First we start with a NEUTRAL pith ball.. Charging by INDUCTION First we start with a NEUTRAL pith ball..

A neutral pith ball has an EQUAL number of Charging by INDUCTION A neutral pith ball has an EQUAL number of

Charging by INDUCTION PROTONS and ELECTRONS!

We’ll now show a representative sample of POSITIVELY Charging by INDUCTION We’ll now show a representative sample of POSITIVELY charged protons in our pith ball.

For the pith ball to be neutral there must be an equal number of Charging by INDUCTION For the pith ball to be neutral there must be an equal number of electrons.

Charging by INDUCTION Remember we are charging the pith ball NEGATIVE by induction therefore we need a POSITIVE rod nearby.

Bring the POSITIVELY CHARGED rod close BUT don’t allow it to touch. Charging by INDUCTION Bring the POSITIVELY CHARGED rod close BUT don’t allow it to touch.

Charging by INDUCTION The electrons in the pith ball are attracted to the positive rod and move close to the rod.

Charging by INDUCTION The electrons in the pith ball are attracted to the positive rod and move close to the rod.

Charging by INDUCTION The electrons in the pith ball are attracted to the positive rod and move close to the rod.

Charging by INDUCTION The electrons in the pith ball are attracted to the positive rod and move close to the rod.

Charging by INDUCTION The electrons in the pith ball are attracted to the positive rod and move close to the rod.

Charging by INDUCTION The electrons in the pith ball are attracted to the positive rod and move close to the rod.

Now touch the positive side of the pith ball with a neutral object. Charging by INDUCTION Now touch the positive side of the pith ball with a neutral object.

This is called grounding. Charging by INDUCTION This is called grounding.

Charging by INDUCTION Electrons from the neutral object flow into the positive side of the pith ball.

Remove the neutral source of electrons. Charging by INDUCTION Remove the neutral source of electrons.

Remove the positively charged rod. Charging by INDUCTION Remove the positively charged rod.

And now you have a NEGATIVELY charged pith ball! Charging by INDUCTION And now you have a NEGATIVELY charged pith ball! NET NEGATIVE

Notice the electrons redistribute themselves. Charging by INDUCTION Notice the electrons redistribute themselves. NET NEGATIVE

Charging by INDUCTION Charging Object The pith ball acquired a net charge that was OPPOSITE that of the charging object by: NET NEGATIVE

Gaining electrons from another neutral object called a ground. Charging by INDUCTION Charging Object Gaining electrons from another neutral object called a ground. Ground NET NEGATIVE

Charging by INDUCTION WOW! NET NEGATIVE

Charging by INDUCTION I luv physicks NET NEGATIVE
