since the equation for torque on a current-carrying loop is $\tau=N I A B \sin \theta,$ the units of $\mathrm{N} \cdot \mathrm{m}$ must equal units of $\mathrm{A} \cdot \mathrm{m}^{2} \mathrm{T} .$ Verify this.

$\mathrm{A} \cdot \mathrm{m}^{2} \cdot \mathrm{T}=\mathrm{N} \cdot \mathrm{m}$

so they form a lout for a talk. Follows turkeys. Number of turns turns multiplied by a current, the magnetic field and an area off Indian Woodrow Look and sign later. And from here we can write that Newton meter. It should mean, um per unit current miles employed by Dessler unit talks the magnetic field multiplied by Mito Square. You need those the area and Santa doesn't have any unit. So, Regis, all the units in a square Burkett and we can see that on the left side we have one meter, and on the right side here we're square. We can can so one meter And we're lived with Newton on the left and I'm parent Esma and meter on the right. And when we remember his formula, which is no one is And I'm personal, which relates force, uh, toe a current and negative failed and length I b l e Just exactly what we have here in units
