Magnets
This material has the ability to attract iron
magnets
What is a condcutor?
a material that allows electricity to flow through it easily
What is the name of the code that is used by electronic devices to communicate information?
binary number system
A continuous unbroken path through which electricity can flow is called...
a circuit
Who discovered that current traveling through a wire produces a weak magnetic field?
Hans Christian Oersted
This is the area of magnetic force around a magnet
the magnetic field
What is an insulator?
a material that does not allow electricity to flow through it easily
This material can work as a conductor and an insulator
A semiconductor
This power source contains one or more electric cells.
A battery
Who is the scientist that worked with Michael Faraday to discover that a magnet moving through or around a loop of wire produces electricity?
Joseph Henry
This is a coil of wire with a core attached to an electrical source
Electromagnet
A measurement of the amount of electrical push or force in a circuit is called?
a volt
This item has two names, and is a very small circuit will all its components in a single unit.
Integrated circuit or microchip
This conductor can be moved to bridge a gap or not in a circuit
a switch
Who is the scientist who discovered adding a metal core to a coil of wire will increase the magnetism?
William Sturgeon
Magnetic force is strongest at the _____ of a magnet.
poles / ends
This is a liquid or paste that conducts electricity
Electrolyte
How do integrated circuits signal information?
They signal information by varying the amount of electricity by opening and closing circuits in sequence.
How do electric cells work?
they use chemical reactions to produce an electrical current
Who is the scientist that worked with Joseph Henry to discover that a magnet moving through or around a loop of wire produces electricity?
Michael Faraday
How are magnets and static electricity similar?
They both attract and repel objects
How much current flows through a given part of a circuit in one second is called...
ampere
Which type of memory stores facts temporarily?
RAM - Random access memory
How are series circuits and parallel circuits different?
Series circuit has only one path for the flow of electricity to follow, while a parallel circuit has multiple pathways for the electricity to follow.
How do generators work?
Electric power plant generators ususally have turbines. The blades of a turbine are moved by water, wind or steam, causing the shaft to spin a magnet inside a coil of wire. The spinning magnet produces electricity in the coild of wire.
Generators use motion to create electricity.
