A coiled conductor shows the same magnetic field as this.

With static electricity like charges _______ and unlike charges _________. Protons are ______ and Electrons are __________.
What is repel, attract, positive, negative?
100
This "list" helps us determine what will become positive and what will become negative when two objects are rubbed together.
What is the triboelectric (electrostatic) series?
100
Device used to detect an electrical charge.
What is an electroscope?
200
An area of magnetic force around a magnet
What is a magnetic field?
200
Like poles ________ and opposite poles ________
What is repel, attract?
200
Controls the heart and other muscle movement inside the body.
What are electrical pulses?
200
When we charge an object this way, the object gets the opposite charge of the object used to charge it.
What is charging by permanent induction?
200
Device used to measure small electrical currents
What is a galvanometer?
300
Paper clip, scissors, hammer will all behave this way since they contain some iron.
What is items attracted to a magnet?
300
A straight conductor makes this shape of magnetic field.
What is a circle?
300
A major example of static discharge that kills approximately 5 people each year in Canada.
What is lightning?
300
These cut off electrical flow if a circuit is overloaded in order to keep us safe.
What are fuses or circuit breakers?
300
This is the energy stored in two unlike charges held a certain distance apart.
What is electrical potential?
400
This can cause a magnet to become demagnetized as the domains become randomly aligned.
What is hitting a magnet very hard? or heating a magnet? or ?
400
This is what causes a force to be exerted on a conductor in an external magnetic field.
What is the motor principle?
400
Benjamin Franklin named ebonite as negative which resulted in this form of current being used as a model rather than "electron flow".
What is conventional current?
400
This individual discovered that a charge moving through a conductor produces a magnetic field around it.
Who is Oersted?
400
Does not allow charges to build up on an object or flow through.
What is an insulator?
500
The angle between the magnetic and geographic poles. It changes in different areas of the world.
What is magnetic declination?
500
This is the fact that energy cannot be created or destroyed when electrons are induced to flow in a conductor (and allows us to predict which way current will thus flow).
What is Lenz's Law?
500
When the number of positive and negative particles is equal, an object is electrically _________
What is neutral?
500
This is the total equivalent resistance through 2 resistors that have 2 ohms connected in parallel.
What is 1 ohm?
500
This method uses heat stored in the earth to generate electricity.
