Electric Charge & Static
These negatively charged particles move around the outside of an atom.
What are electrons
This circuit component converts some form of energy into electrical energy, such as a battery or solar cell.
What is an energy source
All magnets have these two poles.
What is a magnetic field
Double Jeopardy: This scientist discovered the connection between electricity and magnetism in 1820 when he noticed a compass needle moved near a wire carrying current.
Who is Hans Christian Oersted
This is Ms. Delk's favorite drink
Coca-Cola
This occurs when 2 objects rub together causing electrons to transfer from on object to another.
What is friction.
The rate of flow of electric charges is measured in this unit.
What is an amp
Like magnetic poles do this, while unlike poles do the opposite.
What is repel (and attract)
A coil of wire that carries an electric current and produces a magnetic field
What is a solenoid
This is how old Ms. Delk is
What is 26
Materials like plastic, rubber, & glass that prevent electric charge moving easily through them are called this.
What are insulators.
The rate of flow of electric charges is measured in this unit.
What is a series circuit
This term describes the area around a magnet where its force can be detected.
What is a magnetic field
This device uses electromagnets to convert electrical energy into mechanical energy and is found in many appliances.
What is an electric motor
This is Ms. Delk's dogs name
Buster AKA Buster Brown AKA Busta Rhymes
DOUBLE JEOPARDY: This method of charging occurs when a charged object is brought near a neutral object without touching it, causing a rearrangement of charges
What is induction
This property, measured in ohms, represents how much a material opposes the flow of electric current.
What is resistance
Materials like iron, nickel, and cobalt that have strong magnetic properties and can become permanent magnets.
What are ferromagnets
The process where a moving magnetic field causes electric charges in a wire to move, generating current.
What is an electromagnetic induction
DOUBLE JEOPARDY: This is Ms. Delk's favorite thing to do in class
If an atom loses or gains electrons it is called this.
What is an ion.
This factor increases electrical resistance in wires: making them thinner, making them longer, or making them this.
What is hotter
Earth's magnetic North Pole is actually this type of magnetic pole, which is why it attracts the north-seeking end of a compass needle
What is a magnetic south pole
This device uses electromagnetic induction to increase or decrease the voltage of alternating current and is crucial for power transmission.
What is a transformer
This is who Ms. Delk loves the most
Who is ALL her students equally
