## Main Question or Discussion Point

I was just reading through these lecture notes regarding the stresses in solenoids, and came across the following regarding a current-carrying ring orthogonal to a uniform magnetic field,

I wondered if this is a piece of terminology that I haven't come across? To me the total radial force is ##\vec{0}##; they seem to be ignoring that the radial forces (vectors!) on each small piece of the ring cancel when the integral is taken around the whole loop! I hoped someone could clarify whether you'd agree that the above is incorrect. Thank you!
