# Does a square loop carrying a steady current $I$ produce any force?

I have a square loop which carries a steady current as shown below:

I was able to find the magnetic field at the centre of the square loop to be: $$B=\frac{\sqrt{2}\mu_0I}{\pi R}$$

My question is there any force acting on the loop?

• For example does one part of the current-carrying loop exert force on another current-carrying loop.
• Does the current carrying loop being in a magnetic field (its own in this case) case a force any way
