two wires are connected at one end witha half-circle, what would be the magnetic field at the center of the half-circle?

Explanation:

two wires are connected at one end witha half-circle, what would be the magnetic field at the center of the half-circle?

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
