So, this pinch effect force or we can say this Lorentz force or we can say this is pinch effect force, this can be represented as μI square divided by 8Pi , Where mu is called magnetic permeability, what is it called? It is called magnetic permeability.
இதனை μI சதுரம் வகுத்தல் 8π என குறிப்பிடலாம் .
