Magnetic Simulation E

Description:

The cross section of a loop of current carrying wire is shown in the simulation. Current flows toward you (out of the screen) at one end, loops back and flows away from you (towards the screen) at the other end. You can move the loop by dragging it with the mouse. The magnitude of the magnetic field at the mouse location when the mouse is held down.

Question 14:

Which end (blue or red) does the current flow towards you? How do you know this?

Question 15:

Double click in the simulation to see the magnetic field lines. Sketch the loop and field lines. How does the direction of the compass needle correspond to the field lines?
