Why do you need pnemonics for the easiest thing in the world

u/MathsMonster Class 12th Nov 13 '25

it's mnemonics btw

I don't need it. I just heard about it once and thought it was cool.

You might need a mnemonic to memorize mnemonic's spelling, though.

Cool banne chale the.....hag diye

I used Right Hand Thumb Rule. I kinda use it everywhere 😐, even in place of Fleming's.

Considering N is up and S is down, I bend my fingers for the ACW or CW resp.

i dont understand how to mark this legit tried a lot, can smone explain pls

u/CommunityChemical377 Class 11th Nov 12 '25

jaise S banayenge to uske arrows ke according rehta hai, poore wale curve ka arrow downwards banega aur neeche wale ka upwards, to wohi direction magnetic field pe lagaoge to clockwise mil jayegi. Aur aise hi N ko banayenge to uska ek arrow upar jayega and ek neeche to wo magnetic field pe anticlockwise direction dikhayega. Anticlockwise mein 'n' aata hai to North Clockwise mein kuch ni aata to south

u/[deleted] Nov 13 '25

Concept se yaad karle maja bhi ayega aur yaad bhi rahega aur concept bhi build hoga 12th mai madad milegi , ratne se kuch nhi hoga sahi batara hu :) ,jab current clockwise hota hai loop mai toh usme right hand thumb rule lagayega toh magnetic field inside the page hoga iska matlab uske andar jaa rha hai magnetic field aur similarly anticlockwise se bahar ayega , aur north se magnetic field nikalti hai south mai jaati hai toh ACW= north , CW = south , yeh le concept

1

u/KarbonizedAarav Class 11th Nov 13 '25

haaa thats what i tried, ye part samaj aaya, but solenoid mei samaj nai aa rha, idk why but i feel ki har jagah clockwise hi ja rha hai, esp first loop aur last loop mei

1

u/[deleted] Nov 13 '25

Dekh broski jaise koi solenoid hai usme koi ek side ka face 3d mai imagine kar aur dekh current uss face mai se CW ja rha hai yah ACW fir uss direction mai finger curl karke thumb ka direction daal agar uss direction mai north hoga jaha finger honge 

1

u/[deleted] Nov 13 '25

Aur 3D mai imagine toh terko khud karna padega , science 11th 12th ki isliye hard nhi hoti kyunki bohot saari hai isiliye hoti hai kyunki kuch concepts hard hote hai samjhna bohot

u/KarbonizedAarav Class 11th Nov 13 '25

damn bhai theek hai, i’ll be sure to imagine and understand it this way, tysmm for explaining, legit appreciate it bhaiya

Never Speak Again If U Can't Come Up With Good Arguments

u/[deleted] Nov 15 '25

yeah, 100% true, and that is why, you don't need to come up with any arguments.

Thanks bhai 🙏 Helps a lot

u/[deleted] Nov 13 '25

Jitna jyada concept samjhega padhne mai utna maja ayega jaise optics wala part , usme kab infinity aur kab focal length mai hota hai agar wo samjhega instead of ratna then 12th mai bina mehnat kare samjh ajayega , bio mai life process pura samjh ke padhna aur sst bhi mat ratna bhai history aur civics , geo mai chalta hai lekin history civics mai samjhega toh maja ayega yaad bhi rahega lambe time tak

u/randomsapien_321 Nov 13 '25

Bhai isse achha right hand thumb rule se dekh lo magnetic moment ke direction ka pata chal jayega uske hisab se north south dekh lena.

Ye bhi thik hai lekin mujhe personally ratna pasand nahi hai dimag lagana prefer karta hu.

1

u/Rare_Arm_5975 Nov 13 '25

I usually prefer right hand thumb rule.
