試題 :
1. A generator with an adjustable frequency of oscillation is connected to re-
sistance R, inductances $L_1$ and $L_2$, and capacitances $C_1$, $C_2$ and
$C_3$. (a) What is the resonant frequency f of the circuit? What happens to
the resonant frequency if (b) R is increased, (c) $L_1$ is increased, and (d)
$C_3$ is removed from the circuit?

2. Figure shows a loop model (loop L) for a diamagnetic material. (a) Sketch the
magnetic field lines within and about the material due to the bar magnet.
What is the direction of (b) the loop's net magnetic dipole moment μ, (c)
the conventional current i in the loop (clockwise or counterclockwise, face
the +x), and (d) the magnetic force on the loop?
