the vector form of the magnetic force is supposed to be F= ILxB or qv x B and not starting with B though for the magnitude both will give the same value
It's really B x direction of electrons' motion, which is B x the opposite of current, which is B x direction of length vector; length vector is opposite current since current specifies the flow of positive, not negative charge
I'm sorry if this is a stupid question... I'm working on a student experiment at the moment and is slightly confused. If I increased the current in the current-carrying wire (that's between the poles of two magnetic shown in the diagram) wouldn't it increase both the magnetic field and magnetic force? But I cannot have two changing variables. So in this case, would I need to use biot-savart law or still use F=BIL?
how is this man always making physics make sense. i didn't know I had the ability to understand physics. Forever grateful!
how is the force 7.5?
0.5*2*6*0.5= 3
once again, amazing vid! grateful this exists

ye man i confused it should be that way

Good presentation
Love your work but I believe the cross product is l vector cross B vector. Thanks for your time and hard work !!!
Thanks sir, This had helped a lot for my misunderstanding in magnetism.
thnx
Zabed Mohammad Great! You're welcome!
Your videos rock!!!!

Biot_savart law is not applied when we are dealing with elecromagnetism. To find force in a current carrying conductor, we use F=BIL. Hope that helps.
shouldnt the answer be 3 newtons?
