If radius is halved,

Then

As r is inversely proportion to the magnetic strength

New strength is doubled

As ur question is incomplete I can’t tell about length

But my guess it’s lenght of conductor

That is directly proportional to the magnetic strength

im just guessing your question...

New Radius=1/2r

therefore new area of cross section [A]=1/4A

New length= 2l

therefore new resistance= 8 times more than the earlier resistance
