A rod with circular cross-section area 2cm2 and length 40cm is wound uniformly with 400 turns of an insulated wire. If a current of 0.4A flows in the wire windings, the total magnetic flux produced inside windings is 4π×10-6Wb. The relative permeability of the rod is(Given: Permeability of vacuum μ0=4π×10-7NA-2 ) ๐Ÿ“ฒPW App Link - https://bit.ly/YTAI_PWAP ๐ŸŒPW Website - https://www.pw.live
