Suppose a single magnetic compass is set on a wood rail near a current carrying wire. For this and subsequent activities, the compass will always be to the right of the wire, somewhere on the wood track.

1. Sketch predictions for ? vs. R and ? vs. ? graphs.

Assume that an angle of ? = 0 degrees corresponds to the red tip of the compass needing point to the right.

Express your angles in degrees.

For each graph, note what is quantity (quantities) are held constant. Explain your reasoning.
