Electric charge will flow in a circuit when this exists.
What is a potential difference?
A magnet always has these two poles, no matter how many times you break it in half.
What are north and south poles?
This subatomic particle is responsible for electricity in most circuits.
What is the electron?
The direction of an electric field is defined by the force it would exert on this type of test charge.
What is a positive charge?
Like charges do this to each other.
What is "repel"?
In a parallel circuit, if one light bulb goes out, this happens to the others.
What is "they stay lit"?
The magnetic field around a current-carrying wire forms this shape.
What are concentric circles?
Adding a neutron to an atom produces this type of variation.
What is an isotope?
Coulomb's law describes the force between two charges based on these two factors.
What are the magnitude of the charges and the distance between them?
A circuit with multiple pathways for current is called this.
What is a parallel circuit?
If the voltage across a circuit doubles while resistance stays the same, this happens to the current.
What is "it doubles"?
This happens when you place an iron rod inside a current-carrying coil of wire.
What is "it becomes an electromagnet"?
An atom of carbon with 6 protons and 7 neutrons has this atomic mass.
What is 13?
The electric field around a positive charge points in this direction.
What is outward?
Breaking a bar magnet results in this.
What is "two smaller magnets, each with a north and south pole"?
A resistor with a resistance of 60 ohms is connected to a 12 V battery. The current flowing through the resistor is this.
What is 0.2 A?
The direction of the magnetic force on a current-carrying wire can be found using this rule.
What is the right-hand rule?
The number of protons in an atom determines this unique property.
What is the atomic number?
This property of a charged particle determines the strength of the electric field it creates.
What is its charge or magnitude of charge?
Surrounding every moving electric charge are these two fields.
What are electric and magnetic fields?
This is the unit for electric power.
What is the watt?
Earth's magnetic field protects us from these energetic particles.
What are solar wind or charged particles from the Sun?
The particles that hold electrons in orbit around the nucleus are called this.
What are electromagnetic forces?
Two charges are brought closer together. This happens to the electric force between them.
What is "it increases"?
This type of circuit allows current to stop flowing if one element is removed.
What is a series circuit?
