Compute the magnetic field at the center of the semi-circle due to the straight and curved segments shown. b (Technically, to use the Biot-Savart law for currents in a wire, the current must be constant, and the wire must form a closed loop. As a result, there will be a contribution to the magnetic field at the origin due to the parts of the closed loop that are not shown. However, here we assume that the not- shown part of the loop is far enough away that they can be neglected.)arrow_forwardhow does the electrostatic discharge occur in the following situation? explain with suitable mathematical substantiation a.
