(Solution) - In Figure a rectangular loop carrying current lies in the plane -(2025 Original AI-Free Solution)

Paper Details

In Figure a rectangular loop carrying current lies in the plane of a uniform magnetic field of magnitude 0.040 T. The loop consists of a single turn of flexible conducting wire that is wrapped around a flexible mount such that the dimensions of the rectangle can be changed. (The total length of the wire is not changed.) As edge length x is varied from approximately zero to its maximum value of approximately 4.0 cm, the magnitude ? of the torque on the loop changes. The maximum value of ? is 4.80 x 10-8 N ? m. What is the current in the loop?
