To find the circumference of a circle, you can use the formula:
\[
C = \pi \times d
\]
where \(C\) is the circumference and \(d\) is the diameter of the circle.
Given that the diameter of the magnet is 2 inches, we can substitute that value into the formula:
\[
C = 3.14 \times 2
\]
Now, calculate the circumference:
\[
C = 3.14 \times 2 = 6.28
\]
Thus, the circumference of the magnet is
\[
\boxed{6.28} \text{ inches}
\]
