Ampere's Crucital low:- This law states that - Line integral Ħ around the acloreal path is exactly same as consent Pence enclored by the It = magnetic feild internity rame path. طور - E Mo - Permeability of the medium B magnetic feild dennity. Ampere's cirutal low mathematical exprevin Hide = Dend B di Pone Mo Bodi = No tener
Magnetic feild inside" foriod. from ampese circuital love Bodi = Mo Tene Keref file when I cessent flowing through N nog turns then. then tatal current enclored by the path is NXD. Selai 4. I Tene=NI & B di = NI.M Now, B is the B is the magnetie feild of the rodies.
