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
