Atoms
These atoms are negatively charged.
What is an electron?
A push or pull that causes an object to stop, move, or change direction.
What is force?
"Circuitry and Lightbulbs states that this is how we know when current is flowing in a lightbulb circuit.
What is a lit lightbulb?
All types of metals are attracted to magnets.
What is NAH?
A core is.
What is the material around which a coil of insulated wire is wound?
These atoms are positively charged.
What are Protons
A force combining both electric and magnetic forces.
What is electromagnetism?
According to "Circuitry and Lightbulbs" these are some ways in which a modern lightbulb helps save energy.
What is they use less energy to light up, and they heat up less?
There is no electrical current flowing through the circuit.
What is an open circuit?
What is an electromagnet?
A gain of electrons.
What is a negative charge?
The overall forces acting on an object.
What is net force?
In "Electromagnetism", the authors argues that this was Ørsted’s historic discovery.
What is he realized that an electric circuit produced a magnetic field?
This atoms has an equal number of protons and electrons making it nuetral.
What is YAY?
A piece of iron that becomes a temporary magnet when electric currents flow through coils of insulated wire wrapped around it is…
What is an electromagnet?
A loss of electrons.
What is a positive charge?
The object stays still or continues to move at the same speed and in the same direction.
What are balanced forces?
"Electromagnetism" states that this is how you make an electromagnet.
What is running electric current through a long wire, and coil the wire around a core. The magnetic field surrounding each wire wrap adds together for a stronger magnetic net force?
We measure force using Nanometers (N).
What is NAH?
Newtons (N)
Electric forces occur when.
What is when ions create attractive and repulsive forces.
A charged atom.
What is an ion?
Electricity is flowing through the circuit.
What is an open circuit?
"Circuitry and Lightbulbs" describes this path taken by electricity through an incandescent lightbulb.
What is electricity flows into the lightbulb through a contact point in the casing. It flows through an inner wire to the filament, through the filament, then through another inner wire to a contact point in the base.
There is electric energy inside a D-cell.
What is NAH?
Converging is...
colliding,
diverging is dividing,
transforming is sliding,
the Plate Boudaries!
