Chapter 29: Magnetic Field due to currents; Chapter 30 Induction and Inductance, Spring 2023 Question 15 of 22 0.4/1 1 : View Policies Show Attempt History Current Attempt in Progress The simulation (linked below) shows, by default, an end view of one, infinitely long, current carrying wire. The wire lies along the axis and carries current / in the + x direction (out of the screen). A vector plot of the magnetic field is produced (green arrows). which the direction of the field at a point is given by the direction of the arrow and the magnitude of the field by the size of the arrow . We have already studied this magnetic field. It circulates around the wire in a direction consistent with the curled-straight the direction of right-hand rule. Namely, extend the thumb of your right hand in the direction of the current, and the fingers of your right hand curl in on of the magnetic f simulation Building Up a Planar Sheet of Current from Infinitely-Long, Parallel Wires Next, increase the value of N to N = 3. The simulation will now show three infinitely long wires that are parallel to each other, that lie in the xy plane, and that are symmetric about the x axis, The simulation also shows the magnetic field (calculated from the law of Biot and Savart) for the system of three wires. Next, increase the value of N by steps to N = 5, 7,9, 11, 13, and 15. As N increases, the current distribution is an increasingly better representation of a smooth narrow sheet of current that fills the entire xy plane, with calculating the magnetic field produced by a sheet of current that fills a plane. The sheet carries current per unit length (along y direction) denoted by d > 0, where A has the SI unit of ampere/meter. Question 1 Correct! If you extend the pattern of the simulation to the case of a sheet the case of a sheet of current filling the xy plane, you get a uniform magnetic field in the - y directions at all points above the sheet (z > 0), and a uniform magnetic field in the + y direction at all points below the sheet (z 0) or below the sheet (z
