Question

1. For a thin conducting wire carrying current, calculate the value of magnetic field induction
at any point on the conductor itself.​

Answer 1

Answer:

The magnetic field induction at a point P which is at a distance r from the point P is , B = μ04π2Irμ04π2Ir

Now this magnetic field induction at any point on the thin conducting wire carrying current I is ,

B = μ04π2I0   [∵ r =0]=∞μ04π2I0   ∵ r =0=∞

So the magnetic field induction on any point on the thin current carrying conductor is infinite .
