The gray area denotes a magnetic field perpendicular to the screen. You can drag the bar to change the area of the loop. The current meter and the graph show the current induced in the wire. Is the field uniform? If so, what is its direction? If it isn't uniform, describe how it varies. Start.
| Key: The magnetic field varies sinusoidally with distance from left to right. |
