Magnetic field around current carrying coil

We learnt about the magnetic lines of force of a magnetic field produced by a current flowing through a straight conductor. Let us explore its nature when current is flowing through a circular loop of conducting wire.

We will use needle compass, 36 gauge coated copper wire and 4 double A batteries.

Circular coil with a radius of 6 centimeter is made with the help of cardboard sheet and pins.

36 gauge Coated copper wire is wound 60 times.

We will place it on a platform made from cardboard and plastic containers.

Let us sprinkle iron filings with strainer to find the magnetic lines.

When current is flowing thru the conductor, after gentle tapping we can see concentric circles near two areas. This is similar to field lines around a straight conductor.

What about the direction of this magnetic field ?

Let us use a needle compass for the same.

We will place a compass in the center and study the deflection of the needle as current flows through the loop.

As per right hand thumb rule, the needle deflects either northward or southward depending on the direction of current through the loop. It reverses direction as direction of current is changed.

Let us add more needle compass so that we can find the direction of the field around the wire loop on the left and right side.

Needles indicate the direction of magnetic field around the loop. It is as per right hand thumb rule.

Same steps can be followed at the other end as well. Reversing the direction of current, reverses the direction of the field as well.

Do try these different variations to know more about the nature of magnetic field due to current flowing through a loop of conducting wire.

Thank You.

विद्यार्थांना कठीण वाटणारी संकल्पना या प्रतिकृतीने अगदी सोपी करून दाखवली सर, खूप खूप धन्यवाद🙏

1:09 remove coating with sand paper. I was struggling with the experiment at home with different mechanism but after seeing above mentioned step at 1:09, i did it with coil here. My problem got resolved. Thank you so much for your post.

I know this stuff but for someone who does not, this example was well presented.

Bro the Source I'm using getting short Circuited everytime when I turn on the Project Can You Help me?

[mummasrecipehindi]

Sir can you give me a tip then how I can make it for my project work and connect loop to a battery of 9 v

[ashwanisharma]

Can you please tell me if instead of coated copper wire we use uncoated copper wire then it will work or not

[medhachitnis]

Can we get this wire in ordinary hard ware shop.
