HI Everyone,
Experiment No#1:
Click Here 35Mb
(Important, The top
of the coil is the
North pole when the
power is turned on.)
The most important
experiment I have
performed. With the
Schematics we have
been looking at we
can see that there
is, with no doubt,
that if these
circuits are
correctly
calculated, they
will work. Looking
at Faradays Law of
Induction the
Equation is:
The symbol
Φ
(Phi) is from the
Greek Alphabet. We
use this symbol to
represent the
Magnetic Flux in
calculations.

example can be shown
which I have used
from the MIT 802
Lectures,
lecture 17.
= a
B
ω sin
ωt = EMF(t).
a is the area of B,
Magnetic Flux
Density, in where a
conductor is placed
and (ω
sin
ωt) Represents
the Time rate of
change part of the
equation, thus
giving us a sine
wave at the time
rate of change.
A loop of wire is
rotated in the
Earth's Magnetic
Field. There are 42
Turns in the loop.
The Earth's Magnetic
field was measured
at 5 10-5
Tesla. A,
the Area is, a
radius of 30cm,
gives us πR2,
0.28 in sq Meters.

N = 42.
A = πR2
B = 5 10-5
T
Period = 1s -
ω = 2π = 6
Radians/s
EMF(t)
= 42 x 0.28 x 5 10-5
x 6 sin 6t
EMF(t)
= 3.5 milli-Volts
sin 6t
Experiment No#2:
I show here a very
simple way to scan
the Field of a
magnet. Check for
defects and see how
the field works.

Apologies for the
videos, they are a
bit shaky in places.
Well more coming
soon as always.
