Subject: Lorentz force on a current-carrying ring from a straight conductor

Please assume that you have a current-carrying ring and a current-carrying 
straight conductor(length of conductor=diameter of ring). Also, assume that the 
plane of the ring is parallel to the conductor (i.e. both are vertical) and the 
current in both is the same. Do you know if there is a mathematical equation 
for the force that is exerted on the Ring because of the conductor's magnetic 
field? I know that you may calculate it by hand but I'm not sure for the results 
I found. That is why I want your confirmation. This answer doesn't exist in your
archive, this is not a duplicate question, and it has not yet been assigned to a
scientist (I was asked by one of your moderators to add this last sentence.).
