CHAPTER 8 MAGNETIC FORCES, MATERIALS, AND DEVICES \( =333 \) EXAMPLE 8.6 A small current loop \( L_{1} \) with magnetic moment \( 5 \mathrm{a}_{2} \mathrm{~A} \cdot \mathrm{m}^{2} \) is located at the origin while another small loop current \( L_{2} \) with magnetic moment \( 3 \mathbf{a}_{y} A \cdot m^{2} \) is located at \( (4,-3,10) \). Determine the torque on \( L_{2} \). Solution: The torque \( \mathbf{T}_{2} \) on the loop \( L_{2} \) is due to the field \( \mathbf{B} \), produced by loop \( L \). Hence.

Consider the square current loop, case 3 in Figure P20.57 . It has an edge length $L=0.33 \mathrm{m}$ and carries a current $I=7.5$ A. The magnetic field $B=0.22 \mathrm{T}$ is perpendicular to the plane of the loop. What is the magnitude of the torque on the loop?

Consider a square current loop $(L=25 \mathrm{cm})$ that carries a current $I=5.6 \mathrm{A}$ (Fig. $\mathrm{P} 20.59$ ). $\mathrm{A}$ constant magnetic field $B=0.25 \mathrm{T}$ makes an angle $\theta=30^{\circ}$ with the direction normal to the plane of the loop and perpendicular to the line connecting points $A$ and $B$. a. Find the total magnetic force on the loop. b. Assume the loop is attached to a rotatable rod at points $A$ and $B$. Find the torque on the loop.
A square loop $10.0 \mathrm{~cm}$ on a side with 100 turns of wire experiences a minimum torque of zero and a maximum torque of $0.0450 \mathrm{~N} \cdot \mathrm{m}$ in a uniform magnetic field. If the current in the loop is $2.82$ A, calculate the magnetic field magnitude. Example $19-4$
