Faraday's Law of Induction

© http://EduMation.org

A practical demonstration of Faraday's Law. Michael Faraday (1791-1867) discovered the Law of Induction in 1831 after extensive experiments and research. The law states that "the induced electromotive force in a closed loop equals the negative of the time rate of change of magnetic flux through the loop." This video was dedicated to the memory of Michael Faraday. The video was directed and narrated by Mustafa Daif with the help of Younis Ali and Ebtisam Anzoor. This video was produced for EduMation, an educational and training website. The video was shot at Bahrain Training Institute on 7th March 2007.For more educational videos and animations, visit EduMation at: http://msdaif.googlepages.com

Pls msdaif i need to know how a Gaussmeter can be built in application to faradays Law i need a brief explanation please..

[msdaif]

A Gaussmeter uses a Hall-effect transducer to measure the magnetic field. The transducer converts the magnetic field to electric field i.e. from unit of Gauss to volts. A current is composed of moving electrons(charges). If a current-carrying surface is immersed in a magnetic field, the surface charges are pushed to the sides of the surface due to Lorentz force and consequently a voltage is produce in the surface. When I feel free, I'll make a relevant video and I will let you know.

damn terrorists

[msdaif]

What's your problem?

[uhyeh]

What's the magnet support made from? Does it have to be solid in the middle?

[msdaif]

Made of stainless steel

[ducksoup2007]

very true

[Whatitdobitch11357]

OMGZ NUOOHUMUSAH SOUNDZ LIKE TERRORIST HE MIGHT BUILD AND AND COME FOR YOUR CHILD!

[SuperSomanshu]

a very nice demonstration 

[DanishGiirl]

Thank you

[nosmokemonu]

thnk u sir

@100daviddjc Maximum voltage induced when north or south pole facing coil face

[100daviddjc]

Excelent video, I have only one question, how do you put the face of the magnets? north and north facing to inside or one north and one south facing to inside? thanks a lot :-)

@mynameismatt2010 You are right! We could harness energy. Some researchers around the world have developed magnetic suspension systems using your idea. I saw this technology at Osaka University in Japan.

[mynameismatt2010]

If i remember correctly you could move the magnets relative to the coil to get the same result. I wonder if putting very stong magnets inside cars and placing copper coils along freeways could help solve the energy problem. Hahaha. Doubtfull, but it's a nice thought.

@tadm123 Yes

[tadm123]

if you stop moving the coil in the magnetic field the amp meter would read 0 , correct?
