(a) If the equal but opposite current pass the two conductors, find magnitude of the
resulting magnetic field at point (1, 0) in the I - y plane.
(b) At which point would the magnetic field strength be 20% of its value at x = - 0?
(c) Using a computer or by hand, sketch the graph of B(z) from 1 = 0 to z = 3a.
Use this to check your answer in (b).
(d) Repeat (a) with currents passing in the same direction.
(e) WHen is the field B strength maximal for the configuration in (d)?
(f) Using a computer or by hand, sketch the graph of B(1) from 1 = 0 to r = 3a.
Use this to check your answer in (e).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fab2fc186-39f7-41ef-b65e-2783c4bc7e8b%2Fd4c4fb8d-c344-4212-9f4a-37b9f15d2a3c%2Fn9e3xh_processed.jpeg&w=3840&q=75)
