## Homework Statement

A wire is bent into the shape shown in the figure. The semi-circular part has a radius r = 4.00 cm and the rectangular part has a width w = 1.00 cm. A current of 0.300 A runs through the loop. What is the magnitude of the magnetic moment of the loop?

Note: The figure shows a semicircle with a small rectangle at the bottom. Making the rectangle 1cm by 8cm.

## Homework Equations

u=NIA

Area of a circle

A=lw

## The Attempt at a Solution

I have plugged in the values given and added the area of a rectangle to half the area of the circle, and I used one for the amount of loops.

So u=(1)(0.300)((.04^2 pi x0.5)+(.01x.08)

The answer I am getting is 9.9398e-4 which is incorrect. Any help is appreciated! Thanks!
