Chapter 19 Vocabulary Flashcards
The region of magnetic force around a magnet is know as its
Magnetic field
This is the area of a magnet where the magnetic effect is strongest
Magnetic pole
They map out the magnetic field around a magnet
Magnetic field lines
Electrons and protons have a property called
Electric charge
An electric current produces a
Magnetic field
The flow of charge through a material
Electric current
A material in which charges are not able to move freely(because their electrons are bound tightly to their atoms)
Insulators
A complete path through which electric charges can flow
Electric circuit
Uses electrical energy as it interferes with,or resists, the flow of charge
Resistor
A current carrying coil of wire with many loops is a
Solenoid
A solenoid with a ferromagnetic core is a
Electromagnet
Magnet poles that are alike____each other
Repel
The magnetic properties of a material depend on the structure of its
Atoms
The buildup of charges on an object is
Static electricity
The transfer of electrons from a charged object to another object by direct contact is
Conduction
The movement of electrons to one part of an object caused by the electric field of another object is
Induction
The loss of static electricity as electric charges move off an object is called
Static discharge
It creates a potential difference in an electric circuit. It has two terminals(battery)
Voltage
States that resistance is equal to the voltage divided by the current
Ohm’s law
A connection that allows current to take an unintended path is a
Short circuit
The transfer of electrons from one object to another by rubbing
Friction
An electric current will always follow the path of____resistance
Least
There is only one path for the current to take
Series circuit
There are several paths for the current to take
Parallel circuit
