## Homework Statement

Note getting the right answer.

Question:

a). What is the magnitude of the torque on the circular current loop in the figure?

b). What is the loop's equilibrium position.

## Homework Equations

Torque = [(I*A)*B*(sin(theta))]

L= 2.0cm

a= 2.0mm

Iwire = 2.0A

Iloop = 0.20A

## The Attempt at a Solution

First, I tried to find theta using tan^-1(x/y).

Second, I tried to find B, using B= [(1.257E-6T*(m/A)*(I)] /(2*pi*r).

Finally, I tried Torque = [(I*A)*B*(sin(theta))].
