    Your equation for ##\vec{dF} = I \vec{dI} \vec{B}## doesn't make sense as written. How do you interpret ##\vec{dI} \vec{B}##? Is this a product of two vectors? If so, what type of product?

    Later you write ##dT = I \vec{B} \; \vec{dl}##. Again the right hand side doesn't indicate the type of product of the two vectors. Also, the left hand side ##dT## is written as a scalar rather than a vector. It appears that you are assuming that the tension in a segment ##dl## is equal to the magnetic force on the segment. Is that correct? You need to draw a free body diagram for the segment ##dl##.
