Question

A long, straight wire carries a current. Is Ampere's law valid for a loop that does not enclose the wire, or that encloses the wire but is not circular?

Answer 1

Answer:

Explanation:

its valid for any loop.

Its an imaginary loop

Answer 2

Yes, Ampere’s law is valid.

Explanation:

• For a loop, the Ampere’s law is valid because it is not circular. So, it must have few distributions of charge in the enclosed area to have a continuous electric field and a magnetic field that is non-zero in the region.
• Even if there is no own charge distribution in the loop, but if it has influence of the electricity on few other distribution of charge, it can show some magnetic field that is constant  $(\oint \mathrm{B} \rightarrow \mathrm{d} | \rightarrow=\mu \text { oienclosed })$.
