Watched this 8 years ago, now I'm watching to prepare for a Job interview after my masters in chem eng, I just hope everyone in this show is doing something epic.
Diagram at 13:18 (13 minutes and 18 seconds into the lesson) is incorrect. The magnetic field should be in the opposite direction if we are dealing with conventional current.
If may i ask .. If you say that when we put the bar magnet into the solenois the end pole of the bars magnet which is south wil be changed to north too ... im actually not clear about that too
suppose we have a single solenoid ,if we let current flow trough the wire we have a magnetic field,right? but if we put a metal in the core of the solenoid the magnetic field increases its magnitude cuz of the domains inside the metal? and the bigger the area of the metal the greater magnetic field? i just want to get things clear cuz im learning everything at once cuz im in a hurry for exams :d thanks in advance and thanks for the videos ;)
The bigger the metal the higher the resistance to current flow. So to use a bigger metal core, you will need a higher current, and note that the coil must cover almost the entirety of the metal. The metal core acts as a boost BCS the electrons in it will face the direction of the magnetic field created by the moving current. Essentially, if you had a strong enough current and run it through a metal, the metal's electrons will be permanently aligned to a specific direction turning that metal into a permanent magnet. That's basically how they create 99% of the magnets you see every day. I hope this helps the new generation. Stay in school guys, science is amazing and it gets better. One task I'm giving any curious student is: Ever wondered what magnetic fields (aka magnetic field lines) are made of?. I hope you have fun researching the answer.

We wish you all the best with the job interview!
@@MindsetLearn Thanks, I nailed it.

Best explanation,Even after 7 years .

You guys at mindset are so awesome. Thank you guys so much :)
Great lesson ❤️👌

One of the best teachers🙌🙌
Thank you Mlungisi. Wishing you all the best with your studies!
Wow this was 8 years ago
Thanks 💯
You guys rock my soul...
We are glad we could be of help. Wishing you all the best with your studies!
Can someone please send me the link to the facebook page?
I feel awesome...
Solenoids and Circular Coils are two different shapes

Danko!

Nice
Again 😂
When we're talking about the area of the or covered by the magnetic field

Chirombe Miranda 😂😂😂😂😂😂😂😂😂😂dead
😂😂😂😂😂hectic
@@ntsikamzalazala123 😂😂😂he bored me too
Haybo...the English translation is something completely different 😂😂
Sorry sir but dont understand the right hand solenoid rule part 😢
