|-
|00:01
| Hello everyone. Welcome to this tutorial on '''Electro-magnetic induction'''.

|-
|00:06
| In this tutorial we will demonstrate:

* Electro-magnetic induction

* Mutual induction of coils

* Voltage induced by a rotating magnet

* Resonance of driven pendulum.

* And show circuit diagrams for our experiments.

|-
|00:26
| Here I am using,
* '''ExpEYES''' version 3.1.0
* '''Ubuntu Linux''' OS version 14.10

|-
|00:35
| To follow this tutorial, you should be familiar with '''ExpEYES Junior''' interface.
If not, for relevant tutorials, please visit our website.

|-
|00:47
| Let's begin with demonstration of '''Electro-magnetic Induction'''.

|-
|00:52
|In this experiment, wires of 3000 turns coil are connected to '''ground(GND)''' and ''' A1'''.

|-
|01:00
|To show the magnetic effect, a magnet with ''5mm'' diameter and ''10mm'' length is used.
This is the circuit diagram.

|-
|01:11
| Let's see the result on the '''Plot window'''.

|-
|01:15
|A horizontal trace appears on the Plot window. Roll a paper and insert it inside the coil.

|-
|01:23
|Drop the magnet inside the rolled paper and move it up and down.

|-
|01:29
|Repeat the process until the '''induced voltage''' is captured and displayed.

|-
|01:35
| On the '''Plot window''' click on '''Experiments''' button.

|-
|01:39
| '''Select Experiment''' list appears.Click on '''EM Induction'''.

|-
|01:46
| Two new windows, '''Electromagnetic Induction''' and '''Schematic''' appear.
'''Schematic''' window shows the circuit diagram.

|-
|01:56
| On the '''Electromagnetic Induction''' window, click on '''Start Scanning''' button.Horizontal trace changes to a wave.

|-
|02:05
|It happens when the '''periodic scanning''' of the voltage coincides with the movement of the magnet.

|-
|02:12
|This indicates voltage is '''induced''' in the coil by a moving magnet.

|-
|02:18
| Next I will demonstrate '''mutual induction''' of two coils.

|-
|02:23
| In this experiment '''A2''' is connected to '''SINE'''.'''SINE''' is connected to '''ground'''('''GND''') through a coil.

|-
|02:31
|And ''' A1''' is connected to '''ground(GND)''' through a coil.This is the circuit diagram.

|-
|02:37
|Let's see the result on the '''Plot window'''.

|-
|02:40
|Click on '''A1''' and drag to '''CH1'''.'''A1 '''is assigned to '''CH1'''.

|-
|02:47
| Click on '''A2''' and drag to '''CH2'''.'''A2''' is assigned to '''CH2'''.

|-
|02:55
|Move the '''msec/div''' slider to view '''applied waveform''' and '''induced waveform'''.

|-
|03:02
| A changing magnetic field causes '''induced voltage'''.You may not see any '''induced voltage''' on the secondary coil.

|-
|03:12
|Keep the coils close to each other along the axis.Insert some '''ferromagnetic''' material along the axis.

|-
|03:20
|We have inserted a screw driver to '''induce voltage''' on the secondary coil.

|-
|03:26
| Click and drag '''CH1''' to '''FIT'''.Click and drag '''CH2''' to '''FIT'''.

|-
|03:34
|Voltage and frequency of '''A1''' and '''A2''' is seen on the right.

Difference in the voltages of '''A1''' and '''A2''' is due to the '''induced voltage''' on the secondary coil.

|-
|03:47
| Next we will demonstrate '''voltage induced''' by a rotating magnet using '''DC motor''' and coils.

|-
|03:56
| In this experiment,
'''A1''' is connected to '''ground(GND)''' through a coil.

'''SQR2''' is connected to '''ground(GND)''' through a '''DC motor'''.

|-
|04:06
|A permanent magent of ''10mm'' diameter and ''10mm'' length is mounted on '''DC motor'''.
'''A2''' is connected to '''ground(GND)''' through a coil.

|-
|04:18
|This is the circuit diagram.

|-
|04:20
|Let's see the result on the '''Plot window'''.

|-
|04:23
| Under '''Setting Squarewaves''', set the frequency value to '''100Hz'''.Click on '''SQR2''' checkbox.

|-
|04:34
| Click on '''A1''' and drag to '''CH1'''. '''A1''' is assigned to '''CH1'''.

|-
|04:41
|Click on '''A2''' and drag to '''CH2'''.'''A2''' is assigned to '''CH2'''.

|-
|04:47
|Move the '''msec/div''' slider to obtain the wave form.
Move the''' volt/div''' slider to adjust the wave form.

|-
|04:57
|Click on '''CH1''' and drag to '''FIT'''.

Click on '''CH2''' and drag to '''FIT'''.

|-
|05:05
| On the right side you can see voltage and frequency.Please note, voltage and frequency values of the two alternating wave forms are almost the same.

|-
|05:16
|This is because, as the magnet rotates, magnetic field around the coil constantly changes between the poles.

|-
|05:24
|Rotation of the magnet results in alternating '''induced emf''' in the coil.

|-
|05:31
| Next let's experiment with driven pendulum.

|-
|05:34
| If a pendulum oscillates with an '''induced magnetic field''' it is called a '''driven pendulum'''

|-
|05:41
|In this experiment, '''SQR1''' is connected to Ground('''GND''') using a coil.

|-
|05:47
|Button magnets are suspended in front of the coil with a paper strip as a Pendulum.This is the circuit diagram.

|-
| 05:58
|Let's see the result on the '''Plot window'''.

|-
|06:01
|click on '''SQR1''' check box.

|-
|06:05
|Click on '''Experiments''' button.'''Select Experiment''' list appears.Select ''' Driven Pendulum'''.

|-
|06:15
|Two windows appear:
'''Schematic of Driven Pendulum''' and '''EYES Junior: Driven Pendulum'''.

|-
|06:23
| On the '''EYES Junior: Driven Pendulum''' window, drag the slider.
As we drag the slider, the pendulum oscillates.

|-
|06:33
|Between "2.6 Hz" to "2.9Hz" pendulum oscillates with a maximum '''amplitude'''.
This is because its '''resonant frequency''' is same as its '''natural frequency'''.

|-
|06:47
| Let's summarize.

|-
|06:49
| In this tutorials we have learnt to demonstrate:

* Electromagnetic induction

* Mutual induction of coils

* Voltage induced by a rotating magnet

* Resonance of driven pendulum

And Show circuit diagrams for our experiments.

|-
|07:09
| As an assignment, demonstrate

* How to make an electromagnet.

* Mutual induction of a single coil with a magnet.

* Show circuit diagrams for the experiments.

|-
|07:22
|This video summarises the Spoken Tutorial project

* If you do not have good bandwidth, you can download and watch it.

|-
|07:30
|We conduct workshops using Spoken Tutorials and give certificates. Please contact us.
