A Flat Coil Containing 25 Identical Loops Carries $6.4 \mathrm {~A}$

question 136

Short Answer

A flat coil containing 25 identical loops carries $6.4 \mathrm {~A}$ of current. When it is placed in a uniform magnetic field of $0.22 \mathrm {~T}$ that is oriented parallel to the plane of the coil, the magnetic torque on it is $3.7 \mathrm {~N} \cdot \mathrm { m }$ .
(a) What is the magnetic moment of the coil?
(b) What is the area of each loop?
