### 6th Grade Ch 3 Sec 3 Electricity From Magnetism

1. 1. Ch. 3 Sec. 3 Electricity from Magnetism
2. 2. (Electromagnetic) induction <ul><li>Process of generating an electric current by moving a conductor in a magnetic field </li></ul><ul><li>Produces induced current </li></ul>
3. 3. The flow of an induced current may be constant, or may change direction.
5. 5. DC <ul><li>D irect C urrent </li></ul><ul><li>Charges flow in 1 direction </li></ul><ul><li>Used by Thomas Edison </li></ul><ul><li>Type of current found in battery </li></ul>
6. 6. AC <ul><li>A lternating C urrent </li></ul><ul><li>Charges move back & forth in circuit </li></ul><ul><li>Used by Nikola Tesla </li></ul><ul><li>Advantage over DC-voltage can be easily raised or lowered </li></ul><ul><li>Type of current found in homes </li></ul>
7. 7. Bill Nye The Science Guy- AC/DC Charge <ul><li>Well, everybody knows That when electrons flow That flow is known as electricity And although you might say &quot;So?&quot;, without it don't you know You'd be unplugged but not on MTV Now in a battery, current's called DC It flows straight from the minus to the plus But the current in your wall is known as AC, y'all And it cycles back and forth without a fuss. So don't lose that charge, that AC/DC charge Your current alternating or direct 'Cause if you lose that charge, that AC/DC charge There's no reason for a circuit to connect Oooooooh </li></ul>YouTube video-Bill Nye AC DC song
