Question
The magnetic field at the center of a $1.0-\mathrm{cm}$ -diameter loop is $2.5 \mathrm{mT}$a. What is the current in the loop?b. A long, straight wire carries the same current you found in part a. At what distance from the wire is the magnetic field $2.5 \mathrm{mT} ?$
Step 1
Given that \(B = 2.5 \times 10^{-3} \, \text{T}\), \(\mu_0 = 4\pi \times 10^{-7} \, \text{T m/A}\), and \(r = 0.5 \times 10^{-2} \, \text{m}\), we can solve for \(I\). Show more…
