Consider two very long wires, one with a radius of 1mm, and one with a radius of 5mm. Both wires carry the same total amount of current (which is uniformly distributed over the cross-sectional area of each wire). If we measure the magnetic field at a distance of 2cm from each wire separately, which magnetic field will be significantly larger

America Coleman · Answer 1

The magnetic field will be the same for both wires

Explanation:

Because if they have the same current the magnetic field induced in them will b

B inversely proportional to radius r and since radius is same and current is same B will also be same
