A small, square loop carries a 38 AA current. The on-axis magnetic field strength 44 cmcm from the loop is 4.0 nTnT.
Added by James V.
Step 1
We have a small square loop carrying a current (I) of 38 A, and we need to find the magnetic field strength (B) at a distance (r) of 44 cm from the loop, which is given as 4.0 nT. Show more…

A wire carries 6.71 A. You form it into a single-turn circular loop and measure a magnetic field of $42.8 \mu \mathrm{T}$ at the loop center. (a) What's the loop's radius? (b) What's the field strength on the loop axis at $10.0 \mathrm{cm}$ from the loop center?
A single-turn wire loop is 2.8 cm in diameter and carries a 660 mA current. Find the magnetic field strength: A. At the loop center and B. On the loop axis, 28 cm from the center.
