Question

Fill in each blank:

A closed surface necessarily surrounds a volume. It is said to be the boundary to that volume –making a clear distinction between inside and outside. Similarly, a closed (a) _________ is the boundary to an area.

According to Gauss’s Law, if the charge inside some closed surface increases as a function of time, then the (b) ______________ through that surface will increase in time.

But the derivative of charge as a function of time is known (in the lab, for example) as electric (c)_____________ .

And it turns out that something called a (d)_____________ field is produced every time charge flows along a line – as described above.

So, if the electric field in some region of space changes as a function of time, then a new and different field is produced – around the boundary of that space.

The reverse of all the above is also true.

And we can take (f) _______________ derivatives of this function before arriving at the answer 0.

Thus, under certain condition, fields will continue perpetually to ‘induce’ each other – changing in both space and time. Under these conditions, the magnitude and direction of each field experiences a rate of change with respect to space that is related to a rate of change with respect to time.

The particular mathematical relation between these two rates has been seen in physics to apply in other contexts. It is known as a (g) ______order (h) ________ equation.

The equation that describes what the E-field does under these conditions is: (i) __________________________. The equation above describes something traveling as a (j) ______________, propagating at speed:

Explanation / Answer

a) loop

b) Electric Flux

c) Electric current

d) magnetic field

e) q = -(qo w) Sinwt
