Why does the magnet spin and move in the presence of the coil connected to the function generator?
Why does the magnet spin and move in the presence of the
coil connected to the function generator? What role does the
frequency of the function generator play? What role does current
play in this story? What about the Right Hand Rule?

A permanent magnet is held directly below the center of
a coil which is connected to a voltmeter. As you move the magnet
closer towards the coil, the voltmeter reads negative. Which of the
following statements is always true?
Moving the magnet farther away from the coil would produce a
positive voltage reading instead.
Moving the magnet farther away from the coil would also produce
a negative voltage reading.
The closer to the coil the magnet is held in place,...
A resistor, inductor, and capacitor are connected in parallel
with a function generator. Calculate the apparent power of the
circuit.
Enter your answer in VA but do not enter the unit. Round to the
nearest whole VA.
VT = 117V RMS, R = 170Ω, XL = 169Ω, XC = 46Ω
Why a current is generated in a coil rotating between
magnet poles?
Please, for better understanding I need a detailed description.
May be some examples in nature, schemes, and some description based
on basic relations. I want to understand it very well. Would be
nice to get some additional sources to read.
How does rotating the coil in the electric motor affect the
needle of the galvanometer move? Explain why the needle deflects
when the coil in the electric motor rotates.
How do magnetic field lines from the coil compare with those of
permanent magnet? Explain why they have similar shape. What are the
sources of these magnetic fields?
1) What are a Vande Graaf generator and a Tesla Coil? Why aren’t
people hurt when they come in contact with such high voltage?
2) What is the difference between AC and DC? Three prong and two
prong plugs? 110 and 220 plugs?

So why would the Earth, or any planet for that matter, rotate
along an axis? I know of no force which could come into play here,
so i assume it just started off with an initial rotation. But where
did this rotational energy come from? And are there any known
planets which do not rotate?
Assuming no force accounts for earth's rotation, would it be
true that the angular velocity of the earth...
