Term
| Galilean transformation of velocity |
|
Definition
| Allows us to transform a velocity measured in one reference frame into the velocity that would be measured in a different reference frame. The fields are measured at the same point in space by experimenters at rest. |

Term
| Field E' is the induced electric field of |
|
Definition
| Faraday's Law. Which is a statement that a changing magnetic field creates an electric field. |
|
|
Term
| Gauss's Law for magnetic fields |
|
Definition
| We can't enclose a net pole within a surface, and is the mathematical statement that magnetic field lines form closed loops, they don't start or stop, which is why there are no magnetic monopoles. |
|
|
Term
| Electric Flux is independent of |
|
Definition
Capacitor plate size, and the flux is changing with time directly proportional to the charging current.
Φe=Q/ε0
Φe'=I/ε0 |
|
|
Term
| Maxwell hypothesized that the displacement current was |
|
Definition
the "missing" piece of Ampere's Law, so he modified it and now it is called the Ampere-Maxwell Law
∫B·ds=μ0{(r2dQ)/(R2dt)}
dQ/dt = I = the rate the capacitor is charged
∫B·ds = BL = 2ΠrB
R=total radius of capacitor
r= radius of point inside capacitor

|
|
Term
| The electric field of a parallel-plate capacitor |
|
Definition
|
|
Term
| The magnetic field created by a changing E is called |
|
Definition
| The induced magnetic field. Which the change in electric field is equivalent to the magnetic field strength. |
|
|
Term
|
Definition
| Charged particles create an electric field. |
|
|
Term
|
Definition
| An electric field can also be created by a changing magnetic field, and is concerned with the changing magnetic flux through a closed surface. |
