Electric Forces
The force between charged particles
What is electric force?
This object has two poles
What is a magnet?
The relationship between electricity & magnetism
What is electromagnetism?
This device measure electric current, even in small amounts
What is a galvanometer?
A region around charged particles where electric force is exerted on other charged particles or objects. Is invisible!
Who is electric field?
A compass will always point in this direction if there is no magnetic field around it
What is North?
This is a coil of wire with a current running through it
What is a solenoid?
In this device, electricity is supplied, causing a magnetic field that causes motion
What is a motor?
In this, electrons cannot move freely, so this cannot carry a current
What is an insulator?
A magnetic field always travels in this direction
What is North to South?
Increasing the number of loops in a solenoid, or the electric current can increase what?
What is magnetic field?
This device is the opposite of a motor, and uses mechanical energy to create electricity
What is a generator?
This is what causes lightning, or an electric shock when you touch something
What is static discharge?
This powder can help detect a magnetic field
What are iron filings?
Adding this to a solenoid will make it an electromagnet
What is ferromagnet?
