It’s 1 hour and 36 minutes until my final exam, and I just now learned that two loops doubles the i enclosed, and that’s why the B formula can be derived for a solenoid

8:45 - take this a step further by calculating the force that a 0.26T magnetic field would exert on a spring to open a solenoid valve. What would be needed for this calculation?

[@divtec1]

Excellent delivery!

[@waikisatukiki4701]

Thanks a lot sir. No more doubts 😊🙏

[@jcamargo2005]

I am familiar with vector calculus but this kind of stuff is still amazing. Solenoids are a magnific 'exploit', by bending the wire we are shaping the magnetic field to concentrate in the center.

[@AjayKumar-jl1sr]

How about taking a circular loop inside the solenoid? How does ampere's law explains it?(since inclosed current inside is 0 but we know B is not zero)

Using the right hand rule of thumb, nice. There is even sigma notation lambda and some other neat ones, sometimes good symbol does it.

Using the summation rather than the integral makes much more sense... coming from someone who's shaky on calculus still

[@somnathpaul1468]

Sir, you are GOD!☺️

[@manoel737]

Very good. Now my question is: That 0,26 T, equals what force in Newton ? I need to project an electroiman and so, know, how it will be, in terms of N, to LIFT 1 KG ?

[@ahmedabdulkerimyusuf9511]

Sir: Thanks a lot for your helpful teaching. With all respect, a solenoid is a coil of wire sometimes containing a metal core. So, my question is, should the coil be always insulated from from the core? even if it doesn't have a metal core?

[@Snowflake_flora]

Wait.....this wasn't a bob Ross tutorial. Good job sir

[@kabandajamilu9036]

So nice

[@dwinovianto1250]

How about correlation between diameter of wire, diameter of selenoid & magnetic field? thanks.

[@alimokdad6865]

3:20 why you used rectangle instead of circle ?

[@Xerilai]

i think we can take any closed loop (any shape) in space as long as we sum up the B//l along it. here by taking a rectangle you can only consider the line within the solenoid coz the other 3 lines are negligible, hence the b field within the solenoids center axis

[@korzynski]

If the magnetic strength is always in relation to the number of turns per meter, then it seems like increasing the number of turns of wire would have no effect on the strength of the magnet. Assuming the diameter of the wire is unchanged and it can't be coiled any tighter, then increasing the number of turns will increase the length proportionally and they will cancel out. In your example, N=1,500 and l is 5cm, so n=30,000, but if N doubles to 3,000, then l will also double to 10cm and n is still 30,000 and the magnetic force doesn't change. How can this be right?

[@shashvatverma5673]

The strength of the field is to do with density. Even if the solenoid is longer, the density of the turns per coil remaining the same will lead to the same magnetic strength. Id think about how magentic strength is not related to the size of the solenoid

[@mechvex8726]

how did you get u0 mu 0 for the example at the end of the video

[@mechvex8726]

Its a constant

[@mechvex8726]

Oh that makes sense thanks

[@justinalecorellana]

Isn’t what you calculated Mag. Flux density since it’s in Tesla? Also wouldn't you end up with Tesla/Meter as your final units? Why wouldn't you just use B=uIN, since that would give you the total Tesla within the solenoid.

[@MrLightingpower]

Thankyou But I have question. Is magnetic field of solenoid independent of the cross-sectional area of the solenoid?

[@Snowflake_flora]

Yes it is independent

[@YoutubeshortsO.O]

Mam sana ap bi aisay samjahaya karay please🙏

[@mmafridi8928]

I did not get the I(en)= NI and you said that if one loop is 10 Amp then 2 loop 20Amp and so on........ but how? 🤔all the loops in series and same current flows in solenoid instead you increase the loops then current will decrease.

why would the field outside the solenoid be zero?

So the ampere law just show us the formula for solving the strength of magnetic field ?
