Do you know what Faraday’s law is
mathematically?

Do you know the two main ways of changing
magnetic flux?

Do you know why the – sign is placed in Faraday’s
law?

Can you state Lenz’s law?

Decreasing flux?

Do you know what happens to a conducting rod
moving in a Bfield?

Can you find the Efield strength in a moving
conducting rod in a Bfield?

Can you explain why a current turns on when the
area is changing (i.e. the loop/circuit is moving)?

Can you explain why a current turns on when a
Bfield is changing (i.e. dB/dt)?

Can you find emf, current, IL x B forces, v(t),
power, and heat energy when the loop/circuit is moving and the area is
changing?

Can you find emf, current, IL x B forces, power,
heat energy, and the induced circulating Efield when there is dB/dt?

Do you know what an inductor is?

Do you know what an inductor does in a circuit?
And why?

Do you know how to find the energy stored in an
inductor?

Can you derive i(t) in a series LR circuit?

circuit?

di/dt in a LC circuit?

Can you find the frequency of oscillation of
current in a LC circuit?

Can you explain, at least qualitatively, what resistance
does in a LRC circuit, compared to an ideal LC circuit?

Can you explain the gist of how a radio works
(or wireless technology in general), in terms of LC circuits?

Can you explain what the Maxwell displacement
current is?

Do you know what the four Maxwell equations are?

Can you qualitatively explain how you can create
an electromagnetic wave?

Do you know what a transformer is, and how it
works?

Can you explain how various contraptions work in
terms of em induction (think of all the devices in our lab)?
