Dr. Lee ordered the $\rule{3cm}{0.15mm}$ medication stat.

Complete each statement with the correct vocabulary word or words. A(n) ________ can rotate in a magnetic field when a current passes through it.

A small bird (mass $=20.0$ grams) has acquired a charge of $15.0 \mu \mathrm{C}$. How fast would the bird have to fly for the magnetic force due to the Earth's $0.5$-$G$ field to equal $1/10$ the bird's weight? Is this a realistic speed? Assume a $90^{\circ}$ angle between the bird's velocity and the magnetic field.

Explain how the right-hand rule can help you determine the direction of the magnetic field lines around a current-carrying wire.
