What 'creates' and electric field?
Electric charges
What is the direction of an electric field line?
Positive to negative
What is the definitive equation for electric field strength?
E = F / Q
What is Coulomb's Law?
F = (qQ) / (4 * pi * epsilon * r^2)
Apart from the definitive equation, state another equation for electric field strength
E = V / d
Describe the magnetic field pattern of a long, straight current carrying conductor
The field circles the wire, and is strongest near to the wire and decreases in strength with distance from the wire
Describe the magnetic field pattern of a long, current carrying solenoid
Inside the solenoid, the field is very uniform; outside the solenoid, the field is much like a bar magnet and similar to the shape of Earth's magnetic field
