Hans Oersted experiment

You all know that the needle of the compass always points in the #north_south direction
But when a #magnet comes near it, the needle of the
compass deflects. Thus the #magnetic_needle deflects whenever it interacts with another magnetic field.
On this note let's do an activity with an electric cell and a wire. Connect the two ends of the wire to the two terminals of the cell, so an electric current flows through the wire. See the needle of the compass under the wire deflects towards the west. The needle comes back to it's original position when we stop the current.
Now turn the cell to change its polarity. The direction of the current through the conductor changes
The needle now deflects in the opposite direction i.e. towards the east.
Wondering where is the other magnetic field that deflects the needle? Is it the current carry wire? Yes it is!
From this experiment, it was a Dutch scientist named Hans Christian Oersted (1820) who concluded that - A magnetic field is produced around a current carrying conductor. This is called the #magnetic_effect_of_electric_current.
This effect of electricity is used in many appliances like electric fans, mixers, etc.

The practical part is much easier to understand than in books. Thanks for demonstration

[atharvakulkarni]

This is much better explanation than the text book! Thanks a lot! 👍

[SaadShaikh]

Very informative and interesting thanks alot

[gargantuaapocalypsegravity]

I have seen plenty of videos but this seemed way easier to understand. Thanks

[poonamrakheja]

Hats off 2 u. This concept is not clear to students in school which u have cleared in minutes.😂😂😂😂

A nice experiment: simple and direct to the point. However, Oersted original explanation was that there would be an external electric current (or 'conflict') around the wire. The explanation using a magnetic field came with Faraday and Maxwell, some decades after.

[FabioLima-pcdk]

Indeed, in 1822 Ampère succeded in explaining the needle deviation using only a force between current elements (i dL), without fields!

[TheZajkov]

Experiment and explanation are excellent. Only one correction should be done. Oersted was Danish scientist, not Dutch.

[ndvancouveroutdoors]

It would be wise to label the poles of the bar magnet in the demonstration to make it easier to think about for the audience

[nayanagada]

Thanks bro in book i wasn't able to understand but now it's clear

[JustNow]

Ørsted is DANISH not DUTCH. And he was not the first to do this, but otherwise it is OK.

[ishuparthi]

But the wire coated insulation material, so the direction campus deflect or not

[aimgodverse]

Sir wire ko compass ke perpendicular rakhna h ya phir parallel

[raghuramsekhar]

Is 9v battery enough to do this experiment ? 🧐

[crimson_stem]

Just a heads up, he was danish, and not dutch

A minor correction: H C Oersted was a Dane (from Denmark) and not Dutch (from Holland).

In danish the name "Oersted" is spelled "Ørsted"

Apart from that, great video. Thank you :)
