Physics 115 winter 2017 Group Quiz M7 NAME understand 10 points Show all work. Use units. Be neat and organize your work so that can easily it per question currents are in the The figure below shows a long straight wire near a rectangular current loop. Both same plane (z direction is out of the page). 15.0A 7.50 cm 10.0 cm 30.0A H 30.0 cm A. What is the magnetic field (magnitude & direction) generated by the current from the long straight 1) At the upper horizontal leg of the rectangular current loop? (2) At the lower horizontal leg of the rectangular current loop? At the midpoint of the left vertical leg of the rectangular current loop?

Explanation / Answer

A1] B = uo i / 2pir

= 2e-7*15/0.075

= 4*10^-5 T direction is into the page in all

2] B = 2e-7*15/0.175

= 1.71*10^-5 T

3] B= 2e-7*15/0.125

= 2.4*10^-5 T

4] B= 2e-7*15/0.125

= 2.4*10^-5 T
