- Homework Statement:
- What is the magnetic field at the position of the dot in the figure?
- Relevant Equations:
- Cross Product
So when evaluation the cross product of the velocity of the charge and the unit vectors associated with the point I am getting
v x r = j x [ i + j].
Well j x j is 0.
j x i = -k, but yet the answer is positive. Why is this?
v x r = j x [ i + j].
Well j x j is 0.
j x i = -k, but yet the answer is positive. Why is this?
