Can an electric field be compressed?
Electric fields are similar to magnetic fields, and can be "compressed" by the imposition of other electric or magnetic fields.
How are moving electric charges related to electric and magnetic fields?
Moving electric charges create electromagnetic fields.
What is the difference between positive and negative electric fields?
Positive electric fields attract negative charges while negative electric fields attract positive charges.
What do electric fields start with?
Electric fields start on positive charges and terminate on negative charges..
Does electric current create magnetic fields?
Yes, electric current does create magnetic fields

What is a science experiment that demonstrates that magnetic fields cannot be blocked?
Magnetic fields can be blocked. Magnetic fields cannot penetrate a superconductor, and regions can be shielded from magnetic fields using ferromagnetic materials.
What produces the heat during a shielded metal ark weld?
an electric current
How are moving electric charges related to electric and magnetic fields?

Would electromagnetic waves exist if changing magnetic fields could produce electric fields but chaning electric fields could not in turn produce magnetic fields?
no
What is Created by vibrations in electric and magnetic fields?
Vibrations in electric and magnetic fields create electromagnetic radiation.
The strength of electric and magnetic fields remains constant as you move away from the source of the electric and magnetic fields?
yes
Who introduced the concept of 'electric fields'?
Michael Faraday first introduced the concept of electric fields/
