If 39.6 cm of copper wire (diameter = 0.872 mm, resistivity = 1.69

Expert Solution

The radius of the wire can be calculated as follows:

r = 0.396 m / 2(pi)

= 0.063 m

The area of the loop of the wire is,

A_loop = (pi)r²

= (pi)(0.063 m)²

= 0.0125 m²

---------------------------------------------------------------------------------------------------------

The resistance of the copper wire is,

R = (resistivity)(L/A)

= (1.69
