I have the Force
The scientist who published a book titled Treatise on Electricity and Magnetism.
Who is James Clerk Maxwell
These arrows represent the electric field. (page 376)
What is field lines.
This tells you how hard the battery "pushes" electrons through an electrical circuit. (pg 383)
What is voltage.
A cluster of many atoms whose magnetic fields align and so act as a magnet? (pg 393)
What is a magnetic domain.
There are scientists out there looking for a magnetic pole isolated by itself. Scientists call this the search for a magnetic what? (pg 395)
What is monopole.
These are free to move around if there is external energy, such as friction. (page 372)
What is free electrons.
Three ways electrons can transfer from one object to another and can even build up within or on the surface of a material. (pg 377)
What are friction, conduction, and induction.
The rate of flow of electrons moving past a fixed point in an electrical circuit. (pg383)
What is electric current.
Materials that can become permanent magnets. (pg 394)
What is ferromagnectic.
What all magnets are surrounded by? (pg 396)
What are magnetic fields
This scientist discovered that electric forces obey a law similar to Newton's law of universal gravitation. (pg 374)
Who is Charles-Augustin de Coulomb.
This device uses a moving belt to remove electrons, thereby accumulating a positive charge on the metal sphere. (page 378)
What is the Van de Graaff generator
Current that flows from the positive side of the battery to the negative side; this is the way current is drawn in circuit diagrams, even though it is wrong. (pg 386)
What is conventional current
These magnets always come in pairs: one north and one south. (pg 395)
What are dipoles.
This is a lifesaving technology that uses strong magnetic fields. (pg 398)
What is a MRI machine.
In Experiment 11.1 we looked at electrical attraction. Why did your hair stick to the balloon?
When the balloon is rubbed into a persons hair, it picks up electrons, making it negatively charged. Because your hair lost electrons it became positively charged. Opposite charges attract, so your hair was attracted to the balloon and thus stuck up. (Answer found on Figure 11.3 on page 373)
As your feet move over the carpet, you will pick up extra electrons, resulting in a buildup of electricity known as what? (page 377)
What is Static Electricity
These are materials through which electrons can easily flow. (pg 386)
What are electrical conductors.
The force a magnet exerts on another magnet, on metals, or on moving charges. (pg 395)
What is magnetic force.
This is a giant magnet. (pg 398)
What is Earth.
When the distance between two objects increases by a given factor, the electromagnetic force decreases by the square of that factor. (page 375)
What is inversely proportional.
Charging an object without direct contact between the object and a charge. (pg 381)
What is Charging by induction
Electrons move in a current through a material, that material reduces their flow. (pg 387)
What is resistance.
These are simply made of a material whose atoms and domains are arranged in a particular way. (pg 394)
What are refrigerator magnets.
The area surrounding Earth that is influenced by this field. (pg 399)
What is the magnetosphere.
