Tutorial video for Electrical dipole app.
A
I'm
sake
studying
electromagnetic
geophysics
in
university
of
british
columbia,
and
today
I
want
to
introduce
electrical
dipole.
We
chat
and
the
tool
that
we're
going
to
use
is
a
jupiter
notebook.
It's
an
interactive
coding
and
computational
environment,
which
is
really
helpful
for
my
research.
You
know
for
a
lot
of
educational
staff
that
we're
working
on
okay,
so
simply
without
too
much
explanation.
You
click
that
and
then
you
activate
that
cell.
Then
you
pressing
the
shift
enter,
you
can
run
so
we're
running.
The
cells
are
importing
I,
quite
a
bit
of
stuff.
A
Ok,
so
it's
running
give
me
some
warnings,
but
that's
ok,
so
it
ran
its
change.
It
now
and
then
I
want
to
see
some
setups
I've
made
some
potting
function
so,
like
I,
run
this
cell
and
that
run
that
plotting
function
that
I
imported
from
previous
cell.
That
will
provide
this
image.
Ok,
so
we
have.
This
is
like
a
setup
for
cross.
Well,
II
am
a
survey
that
we're
going
to
deal
with
use
and
to
provide
some
context
of
geophysics.
So
we
have
a
two
boreholes
at
like
this.
One
is
a
transmitter.
A
Holes
with
transmitter
is
located.
So
here
the
transfer
could
be
plus
and
minus
electrodes,
so
we
attach
that
a
plus
and
minus
electrodes
to
the
well
through
the
well
and
so
basically
to
the
earth,
and
then
we
can
inject
the
current
from
plus
to
minus
electrodes.
So
the
current
will
flow
in
the
ground,
so
current
will
flow
and
something
like
that.
The
current
flow
will
make
a
potential
difference
and
at
the
receiver
locations,
and
we
can
measure
that
potential
difference
made
by
current
flow
and
like
yeah.
A
So
that's
like
a
sort
of
problem,
but
if
we
have
some
cognitive
e
contrast
and
ears,
for
example,
if
you
have
gold
that'll
make
a
different
County
revalue
from
the
background.
Ecology,
beauty
and
the
current
path
will
be
distorted
due
to
that
commentary.
Contrast
from
the
gold-
and
we
measure
that
distorted
responses
from
your
see
the
location
and
at
somehow
by
interpreting
that
we
want
to
image
the
conductivity
structure
of
the
earth
here.
And
if
you
want
to
do
that.
A
Well,
we
really
need
to
understand
what's
happening
in
the
earth
when
we
are
exciting
the
system
by
using
some
electromagnetic
sources.
Okay
and
well
like,
if
you
put
a
constant
current
that
can
be
considered
as
a
DC,
so
static
problem,
but
if
you're
putting
senior
soil
current
with
a
certain
frequency
that
can
be
considered
as
a
frequency
domain,
eam
survey
and
in
that
case,
depending
on
frequency,
there
can
be
a
lot
of
physical
thing
is
happening.
A
There
can
be
some
set
of
charge
build-up,
but
also
there
can
be
an
induction
but
like
if
you
go
really
high
frequency
they're
going
to
be
a
wave-like
feature
as
well,
which
sometimes
we
use
as
a
GPR.
Okay,
so
they're
like
enough
complexity
or
complex
physics
happening,
and
we
really
need
to
know.
We
really
want
to
know.
What's
what's
that
is,
and
we
want
to
see
how
the
fields
looks
like
based
upon
that
and
that's
sort
of
the
goal
of
making
these
widgets
and
then
sort
of
presenting
it.
A
So
here,
let's
assume
the
capital
F
with
bald
faced
as
a
en
field
which
which
is
a
vector
and
then
that's
complex
value,
because
we're
in
the
frequency
domain
and
that's
a
function
of
XYZ
application,
so
3d
and
it's
a
function
of
concavity
and
frequency.
So
it's
pretty
complex
function
and
then
here's
our
setup.
It's
a
cross
well
p.m.
set
up
and
we're
interested
in
3d
volume.
So
why
we're
gonna
run
this
bridge
yet,
but
like
thinking
about
vectors
in
3d,
is
actually
pretty
pretty
complex,
so
we're
gonna
sort
of
narrow
it
down.
A
So
we're
going
to
focus
on
certain
plane
that
we
are
interested
so
like
this
one
is
XZ
plane,
but
you
could
choose.
Why
is
that
planning?
If
you
want
and
then
you
could
move
your
plane
like
by
changing
this
offset
value?
So
if
you
want
to
see
the
receiver
plane
and
15
okay-
okay,
it's
about
that.
But
if
you
want
to
go
back
to
the
default,
you
can
just
rerun
that
will
go
back
to
default.
So
this
is
like
say
assuming
that
I'm
interested
in
XZ
plane
at
a
receiver,
and
then
we
run
this.
A
So
I
want
to
see
the
electrical
fields
at
that
receive
a
plane
and
then
that
all
pop
up
pretty
soon
okay.
So
this
is
the
vector
fields
at
exit
points.
Remember
our
very
collectible
dipole
was
here.
So
why
so?
It
seems
like
plus,
is
here
plus
is
here.
Then
line
goes
like
that
that
and
then,
if
you
look
at
the
receiver
location
that
looks
like
this,
so
that
looks.
A
That's
like
a
measured
data
will
be
looks
like
in
your
bowl
hole,
okay,
but
definitely
it's
a
vector
feel
so
well,
but
like
guys
like
just,
we
could
break
apart
as
accents
that
component.
So
let's
assume
that
I
want
to
see
the
Z
component
and
will
I
change
the
scalar
and
then
I'll
show
you
the
z
component,
which
was
like
that's
remember,
those
go
down
so
minus,
and
but
that
was
like,
if
you
look
at
the
y
component,
that'll
be
cool.
A
Nothing
because
Y
component
is
0,
there's
some
singularity
and
that's
X
component
that
and
remember
we're
using
zero
frequency.
This
is
DC
regime,
so
like
there's,
no
imaginary
part
but
yeah.
Ok,
so
that's
what's
happening,
but
you
could
change.
You
can
increase
the
frequency
that
will
be
different.
Ok,
but
let's
not
go
there,
but
I'm
now,
I'm
interesting
that.
Why
is
that
fine,
so
I
still
same
like
remove,
want
to
move
to
where
receiver
is
so
at
the
receiver?
A
A
A
This
changing
scale
gives
you
different
ideas.
So
that's
a
linear
scale
and
well.
So
this
is
a
vector
field,
but
I
want
to
see
now
is
that
component,
so
I've
changed
to
scalar
yeah.
So
that's
like
that's
really
typical
dipolar
response
for
certain
components.
Right,
remember
that
was
going
down,
so
that
gives
us
minus
right
and
some
plus
here
and
there,
which
sort
of
makes
sense.
A
So
this
is
slide,
we're
expecting
so
if
the
earth
is
homogeneous
and
then
if
you
do
the
survey
of
course
well
and
then
for
a
single
source,
if
you
look
at
the
receiver
data
at
all
of
your
receiver
location
in
the
vertical
hole
that
will
be
looks
like
that,
okay,
so
it's
kind
of
nice
to
have
that
idea
before
you
start
right
and
well
now
you
could
think
about.
We
can
think
about
measuring
magnetic
field,
then
that
will
be
different
right
and
then,
by
choosing
like
this
magnetic
field,
you
could
serve
think
about
that.
