Hey man, thanks, it's people like you that fill the gaping holes that our professors leave. Thanks for making the concepts much more obvious, it makes it that much easier to solve these problems.
Thanks, SideShockGame. You're absolutely right. I should've solved for both the magnetic force AND the electrostatic force. I've added an annotation in the video. I appreciate the help.
your explanation is very clear but i request u to put some videos on magnetic field on a current carrying circular or semicircular loops (solutions for the questions) which have some angles in them.............. thumbs up!
To find the direction of the force on wire 1 due to 2, first find the direction of the B field from 2 at the location of wire 1. This uses a right hand rule (thumb is dir. of I(wire 1), curled fingers show direction of B). Then find the direction of the force on wire 1 using a different right hand rule (thumb is dir. of I(wire 2), fingers are dir. of B from wire 2, palm points in direction of force on wire 1)
strange, if you have two electrons stationary , they repel each other (static force), but if you take these same two electrons and shoot them down a parallel path, they then attract each other (two parallel line currents in same direction). if two static electrons are placed north and south on the earth, shouldn't the electrons attract each other since the are both travelling parallel due to the direction of the earth's rotation (parallel line currents) ?
You would have to consider the magnitude of the electrostatic force (the one responsible for repelling) and the magnetic force (the one that attracts). For the electrons, the electrostatic force always forces them apart, but if they are moving at sufficient speeds (i.e. if the magnitude of current is high enough) the magnetic force can overpower the repelling force and bring them together.
@@anuragyadav_8572 reply after 2 years... it's 4pi*r^2 because u have two velocities (units m/s each) in the numerator. Before, it was only L at the top (units m). Now you have m^2 at the top so u need an m at the bottom to make it the same. If u do the math it ends up being the same as the previous equation.

i have doing this problem for almost 2hours and was fully confused but you help me lot LOVE you from iran
Hello and I'm from 2020 and this is super useful
Hey, thanks for all your EM videos they have been a great help^^

Great videos! They've been a big help.
thanks! exam soon and this helped so much
if there are two wires parallel to each other than the force between them would be attractive or repulsive???plz tell
According to the wire on the right wouldnt the magnetic field on the inside be going into the page??????
What if the magnitude of each current is different? Would that affect the direction of the field in some way?
In the last example isn't theta the angle between v and r?
no its the angle between b and v
What if the current direction on both wire opposite?
Jack Ho are you for real
Liam E yes i am
+Jack Ho You would get the exact same result as shown in the video.
+Jack Ho that's exactly what he did lol one . and one x
your explanation is very clear but i request u to put some videos on magnetic field on a current carrying circular or semicircular loops (solutions for the questions) which have some angles in them.............. thumbs up!
why is the B total only in the y direction ?
+Nasser Alfaraj The values in the x direction cancel out
Can anyone explain why the magnetic field for the last problem is what it is. I dnt understand how he got it
i can but it's been 4 years...
@@MAliK-ox2lz please explain!
How can you find the direction of force due to wire 2
To find the direction of the force on wire 1 due to 2, first find the direction of the B field from 2 at the location of wire 1. This uses a right hand rule (thumb is dir. of I(wire 1), curled fingers show direction of B). Then find the direction of the force on wire 1 using a different right hand rule (thumb is dir. of I(wire 2), fingers are dir. of B from wire 2, palm points in direction of force on wire 1)
Is L, L1 or L2?
So cool and realistic
lol the end sounded like he was ending a phone conversation
parallel current attract and anti parallel current repel
You would use Ampere's law to get that. "Ampere's Law" is another ten minute video.
Thank you.

Distance is r , not r^2 on the last problem , ı guess
though this reply is after 4 years but still my doubt is same why is r squared
