    It's crazy how paid teachers have much lower efficiency in delivering the knowledge than you guys, if I one day become rich I would like to support you guys handsomely!

    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?

      We know r is a unit vector

      Since, |r| = r
      So, put the value of r^ then you get r³

      @joenuts3308 3 месяца назад

      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
