suppose that when you move a magnet through a boiba 40 turns at a certain speed, it induces an electric potential of 10 v through the coil .. if you move the same magnet through a coil 80 turns to the same speed. what voltage will be induced on the coil, assuming both coils are very compacted?
a) 20 v
b) 5 v
c) not enough information
d) 10 v

A) A conducting rod moves through a magnetic field at a constant speed. Why does the induced potential not continue to increase indefinitely? B) How can an electric field be produced without any charged objects? C) A transformer is formed when two coils are placed close enough that the magnetic field of one causes magnetic flux through the second? A changing current in one coil thus induces a current in the second. Why do you suppose transformers are not used...

If the average current passing through the secondary coil of the transformer with 40 turns and a secondary voltage of 24-V AC is 10 A, what average current is passing through the primary coil that makes 200 turns and has a primary voltage of 120-V AC?

When you drop a magnet (North Pole first) through a large coil and measure the induced voltage over time, you will notice that the induced voltage has one peak upward and one peak downward. Explain why this happens. You will also notice that these voltage peaks are not the same magnitude, but the area under the peaks are nearly the same. Which peak is larger, the earlier or the later one? Explain why. What do the areas represent and why are...

In the figure below a thin coil of radius r1= 4 cm, containing
N1= 5300 turns, is connected through a resistor R = 100 Ω to an AC
power supply running at a frequency f= 2100 so that the current
through the resistor (and coil) is I1sin(2π×2100t). The voltage
across the resistor triggers an oscilloscope that also displays
this voltage, which is 10 V peak-to-peak and therefore has an
amplitude of 5 V (and therefore the amplitude of the current...

You throw a bar magnet downward with its south end pointing down
(see figure below). The bar magnet has a magnetic dipole moment of
1.6 A·m2. Lying on the table is a nearly flat circular
coil of N= 1175 turns of wire, with radius R= 6 cm. The coil is
connected to an oscilloscope, which has a very large
resistance.
At the instant when the magnet is h= 30 cm above the table, the
oscilloscope indicates a voltage of magnitude...

transformers
Learning Goal: To understand the concepts explaining the operation of transformers.One of the advantages of alternating current (ac) over direct current (dc) is the ease with which voltage levels can be increased or decreased. Such a need is alwayspresent due to the practical requirements of energy distribution. On the one hand, the voltage supplied to the end users must be reasonably low for safety reasons(depending on the country, that voltage may be 110 volts, 220 volts, or some other value...
