Consider an extremely long wire carrying 165.5 A of current along the $y$ axis (flowing in the $-y$-direction) in a Cartesian coordinate system. At $t = 0.0$ s, you launch a charged bed of $4.5 \times 10^{-5}$ C from a position of $(0.9 \text{ m}) \hat{i} + (1.3 \text{ m}) \hat{j}$ with an initial velocity of $(354.6 \text{ m/s}) \hat{i} +$ $(-976.4 \text{ m/s}) \hat{j}$. (a) Qualitatively, draw the magnetic field generated by the wire in the $xy$-plane at a bunch of different observation points in the space surrounding the wire (at least 20 observation points). (b) Qualitatively, draw a graph of the $z$-component of the magnetic field coming from the wire versus position along the $x$-axis. (c) What is the $x$-component of the magnetic force on the bead at 0.0s?

The point at which an economy turns from expansion to contraction is called a business-cycle peak. Economic growth is typically steady and occurs without many short term fluctuations between expansion and contraction. Unemployment is typically increasing in the time leading up to a peak. The point at which an economy turns from contraction to expansion is called a business-cycle depression. It is possible that the economic output associated with a nation's most recent business-cycle trough is higher than the economic output associated with an earlier business-cycle peak. Recessions are related to GDP, and therefore, are unrelated to business cycles.
