Electric fields
What part of the field is the strongest
The ends
What do the lines in a negative charge point to?
Inwards
do atoms make up everything we see?
yes
What is in the middle of a plasma globe?
an electrode
What is a electromagnet?
a soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
Can you see the lines in an electric field?
No,they are invisible.
What do the lines in a positive charge point to?
Outwards
What are atoms made of?
An atom itself is made up of three tiny kinds of particles called subatomic particles: protons,neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus in a small cloud.
define electrode
a conductor through which electricity enters or leaves an object, substance, or region.
What is a solenoid?
a cylindrical coil of wire acting as a magnet when carrying electric current.
Do all electric fields have the same size and strength.
No they do not.
How do opposite charges interact
they attract
how many atoms are in a cell.
100 trillion
What happens when the electrons touch the gases?(Argon,Neon,Xenon)
It produces light
How do you make an electromagnet stronger
Add more loops to the coils or add more batteries.
What is an electric field?
a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
They repel
define atom
an extremely small amount of a thing or quality.
What happens when you put a light bulb near a plasma globe?
It lights up
Are two solenoids a magnet?
No
Are all electric fields always weak?
No,some are strong .
define electric charge
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charges; positive and negative (commonly carried by protons and electrons respectively). Like charges repel and unlike attract.
What are photons?
a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.
What happens when you pull away the light bulb from the plasma globe
It flickers a little.
How do you strengthen a solenoid.
