Answer
$\mu=0.30 A.m^2$
Work Step by Step
The magnitude of the magnetic dipole moment can be calculated from the formula:
$\mu=iA$
To use this formula, we first need to find the area of the triangle:
$A=\frac{1}{2}(0.30\times 0.40)=0.06m^2$
We plug in the known values to obtain:
$\mu=5\times 0.006$
$\mu=0.30 A.m^2$
