turning the turbine
100
these poles attract each other
What is North and South (opposites)
100
wire wrapped around an iron core that when it is carrying an electric current makes the iron core magnetic
What is sollenoid
100
uses an electromagnet to convert mechanical energy into electrical energy
What is a generator
100
this kind of energy is used to make either the permanent magnet or the coil spin to produce a current in the coil
What is mechanical energy
100
source of mechanical energy in a crank flash light
What is you or me
200
These poles repel each other
What is North and North or South and South (like)
200
this device uses an electromagnet to measure electric current.
What is galvonometer
200
a device that increases or decreases voltage of electric current passing through a power line
What is a transformer
200
generating an electric current by changing the magnetic field
What is magnetic induction
200
These are used to convert wind energy to electrical energy
What is a windmill
300
this type of magnet keeps its charge for a long time
What is permanent
300
works when an electromagnet and a permanent magnet are connected to an electric source
What is electric motor
300
this type of current reverses itself in a regular pattern
What is AC (alternating current)
300
generators found in cars are called this.
What is the alternator
300
the currents in these can be use to turn turbine blades if the power plant is right next to it.
What is rivers or streams
400
in this all of the atoms with aligned magnetic poles
What is magnetic domain
400
a wire carrying an electric current wrapped around an iron core
What is electromagnet
400
this current flows only in one direction
What is DC (direct current)
400
this kind of transformer increases the voltage before transmission to reduce loss of energy through heat
What is step up transformer
400
coal is burned to boil water to make this to turn the turbine
What is steam
500
this becomes stronger as the magnets get closer together
What is magnetic force
500
adding more turns to the wire does this to the strength of the magnet
What is increases
500
a large wheel that rotates when pushed by water wind or steam to generate electricity
What is A turbine
500
this type of transformer decreases voltage to 120 v for use in your home
What is step down transformer
500
This landmark in Fort Wayne used to be the electrical power plant and has turbines for the public to see.
