Your explanations are awesome 👌. So many concepts in just one video.This kind of study material will get any student interested in the subject. I don't think I have to revise it again. Thank you so much.
@@Devilhunter69 college tends to deepen what you learn in highschool in my experience. well actually i'm in university but anyway. i'm doing computer science so the physics level is closer to high school level but still bit higher than what i learned in highschool. it uses basically the same material but has more explanation and where the formulas are from and uses more calculus.
You have to use r^3 if you dont use the unit vector. the guy used unit vectors which is why he uses r^2. for more info you can look at the english wikipedia article about biot-savart
@@user-cc7ks7re3w the other explained it pretty well, you can either use unit vector in the direction of radius to denote the vector for radius, or just simplify the unit vector which turns out to be *r* /r , plug this value instead of unit vector and you'll get the textbook equation
Isn’t this finding just the magnetic field as it is affected by the length of dl? So to find the total force applied on a single point you would need to do multiple equations? Or should you just use the perpendicular measurement (since it is where force is strongest) for an estimate?
by any chance were you born in South India and moved to New-York or California?? Just curious about your accent. Great video by the way it was very very helpful

Concept: Vectors - Cross Product Suppose we have two vectors, A=2i+3j and B=4i−j where i and j are unit vectors along the x and y axes, respectively. The cross product A×B is given by: A×B= ∣ i j k ∣ 2 3 0 4 -1 0 Now, calculating the cross product; A×B=(3×0−(−1)×0)i−(2×0−4×0)j+(2×(−1)−3×4)k we get: AxB =0i-0j-12k A×B= −12k. [It is in the negative z- axis] But in this case if we do B x A: By doing the same method again as shown above but putting values accordingly. Mathematically the relationship is expressed as: B x A = - ( A x B ) A x B= -12 (as calculated) B X A = - (-12k) = +12k [it is in Positive Z axis] Difference in the direction!! Similarly, we cannot write r x dl.
In his equation, he has taken the unit vector of r that is r cap. But in textbook it is vector r which is equal to the unit vector times the magnitude of r so we have to multiply r on numerator and denominator to get db = μ0/4π x I dl × vector r/r^3
I appreciate your efforts. But you lacked in explaining why magnetic field changes when we change angle. You just explained the effect but skipped the cause...!

Sir can you make video on Capacitor RC circut?
Hey here's a doubt, our NCERT books say idl*r^
^3 but u hv written r^2 instead of r^3 so which one's right?
hello kaushik rcap can also be said as r vector . r = so it becomes rvector / r^3
Did you mean by substituting r cap=(r vector/magnitude of r vector)?

Is it r^2 or r^3 in vector form, i am confused.
Isn’t this finding just the magnetic field as it is affected by the length of dl? So to find the total force applied on a single point you would need to do multiple equations? Or should you just use the perpendicular measurement (since it is where force is strongest) for an estimate?
Better use slap rule than right hand Fleming rules .... Arun maheshwari sir though me slap rule you could enjoy this rule than Fleming rule
Theeeee BEST
Sir in NCERT it is given that in vector form the distance is r^3 but you mentioned it as r^2...please clarify it
We know r is a unit vector
So, r^ = r(vector)/ |r|
Or, r^ = r(vector)/r
Since, |r| = r
So, put the value of r^ then you get r³
by any chance were you born in South India and moved to New-York or California?? Just curious about your accent. Great video by the way it was very very helpful

why only dl vector cross r vector why not r vector cross dl vector. Could anyone explain or which one of your videos explain this?
Concept: Vectors - Cross Product
Suppose we have two vectors,
A=2i+3j and B=4i−j where i and j are unit vectors along the x and y axes, respectively.
The cross product
A×B is given by:
A×B= ∣ i j k ∣
2 3 0
4 -1 0
Now, calculating the cross product;
A×B=(3×0−(−1)×0)i−(2×0−4×0)j+(2×(−1)−3×4)k
we get:
AxB =0i-0j-12k
A×B= −12k. [It is in the negative z- axis]
But in this case if we do B x A:
By doing the same method again as shown above but putting values accordingly.
Mathematically the relationship is expressed as:
B x A = - ( A x B )
A x B= -12 (as calculated)
B X A = - (-12k)
= +12k [it is in Positive Z axis]
Difference in the direction!! Similarly, we cannot write r x dl.
Why is it r^3 in my textbook not r^2..
In his equation, he has taken the unit vector of r that is r cap. But in textbook it is vector r which is equal to the unit vector times the magnitude of r so we have to multiply r on numerator and denominator to get
db = μ0/4π x I dl × vector r/r^3
