02:40	Nion ha u A1 bad tan sha u CH1. A1 lah assigned sha u CH1.
02:47	Nion ha u A2 bad tan sha u CH2. A2 lah assigned sha u CH2.
02:55	Pyniaid ia u msec/div slider ban view ia ka applied waveform bad induced waveform.
03:02	Ka jingkylla jong ka magnetic field ka pynlong ia ka induced voltage. Phi lah ban nym iohi induced voltage ei ei ha u secondary coil.
03:12	Buh marjan ia baroh ar tylli ki coils ha ka axis. Thep katto katne ka ferromagnetic material ha ka axis.
03:20	Ngi lah thep ia u screw driver sha ka induce voltage ha u secondary coil.
03:26	Nion bad tan ia u CH1 sha u FIT. Nion bad tan ia u CH2 sha u FIT.
03:34	Voltage bad frequency jong u A1 bad A2 lah iohi ha ka liang kamon. Ka jingiapher ha ki voltages jong u A1 bad A2 kadei namar jong ka induced voltage ha u secondary coil.
03:47	Hadien kane, ngin ia batai ia ka voltage induced da ka rotating magnet da kaba pyndonkam ia ka DC motor bad ki coils.
03:56	Ha kane ka experiment, A1 lah connected sha u ground(GND) lyngba u coil. SQR2 lah connected sha u ground(GND) lyngba u DC motor.
04:06	U permanent magnet uba 10mm diameter bad 10mm ka length lah pyndait ha u DC motor. A2 lah connect sha u ground (GND) lyngba u coil.
04:18	Kane kadei ka circuit diagram.
04:20	To ngin ia peit ia ka result ha ka Plot window.
04:23	Hapoh u Setting Square waves, set ia ka frequency value sha 100Hz. Nion ha u SQR2 check-box.
04:34	Nion ha u A1 bad tan sha u CH1. A1 lah assigned sha u CH1.
04:41	Nion ha u A2 bad tan sha u CH2. A2 lah assigned sha u CH2.
04:47	Pyniaid ia u msec/div slider ban ioh ia ka wave form. Pyniaid ia u volt/div slider ban antad ia ka wave form.
04:57	Nion ha u CH1 bad tan sha u FIT. Nion ha u CH2 bad tan sha u FIT.
05:05	Ha ka liang kamon, phi lah ban iohi ia ka voltage bad frequency. Sngewbha kynmaw, voltage bad frequency values jong ar tylli ki alternating waveforms ki jan ialong mar kumjuh.
05:16	Kane kadei namar, katba ka magnet kadang rotate, ka magnetic field sawdong jong u coil ka kylla hapdeng ki poles.
05:24	Ka jing rotate jong ka magnet ka pynlong ia ka jingkylla u induced emf ha u coil.
05:31	Hadien kane, to ngin ia experiment da u driven pendulum.
05:34	Lada u pendulum u khih shane shatai bad ka induced magnetic field, la khot ia ka driven pendulum.
05:41	Ha kane ka experiment, SQR1 lah connect sha ka Ground (GND) da kaba pyndonkam da u coil.
05:47	Button magnets lah suspended hakhmat jong u coil da u paper strip kum ka pendulum. Kane kadei ka circuit diagram.
05:58	To ngin ia peit ia ka result ha ka Plot window.
06:01	Nion ha ka SQR1 check box.
06:05	Nion ia u Experiments button. Select Experiment list kapaw. Jied Driven Pendulum.
06:15	Ar tylli ki windows ki paw- Schematic jong ka Driven Pendulum bad EYES Junior: Driven Pendulum.
06:23	Ha ka EYES Junior: Driven Pendulum window, tan ia u slider. Katba ngi dang tan ia u slider, u pendulum u khih.
06:33	Hapdeng "2.6 Hz" haduh "2.9Hz" ka pendulum ka khih bad u maximum amplitude. Kane kadei namar, ka resonant frequency jong ka kalong kumjuh kum ka natural frequency.
06:47	To ngin ia batai kyllum.
06:49	Ha kane ka jinghikai, ngi lah pule kumno ban batai ia ka: Electromagnetic induction Mutual induction jong ki coils Voltage ba lah induce da ka rotating magnet Rosanance jong u driven pendulum bad pyni ia ka circuit diagrams na ka bynta ka experiments jong ngi.
07:09	Kum ka assignment, batai: Kumno ban pynlong ia ka electromagnet Induction jong uwei u coil ryngkat ka magnet Bad pyni ia ka circuit diagram na ka bynta ki experiments.
07:22	Kane ka video ka kyllum lang ia ka Spoken Tutorial project. Lada phim don ia ka bandwidth kaba biang, phi lah ban shu download bad peit ia ka.
07:30	Ngi pynlong ia ka workshops da kaba pyndonkam ia ki Spoken Tutorials bad ai certificates. Sngewbha thoh sha ngi.
07:37	Ia ka Spoken Tutorial Project la beit pisa da ka NMEICT, MHRD, Sorkar India.
07:44	Ia kane ka jinghikai la noh synniang da U Pdiangburom na Shillong. Khublei shibun.
