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 6 mV.
What is the speed v of the magnet at that instant?
m/s

A coil with 3300 turns and radius 5 cm is connected to an
oscilloscope (see figure below). You move a bar magnet toward the
coil along the coil's axis, moving from 39 cm away to 27 cm away in
0.2 s. The bar magnet has a magnetic moment of 0.8
A·m2.
(a) What is the approximate magnitude of the signal observed on the
oscilloscope? (Calculate the average emf.)
mV
(b) What approximations or simplifying assumptions did you make?

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...

Also, if you happen to have any idea of what book this came out
of (or one that has very similar problems) I would GREATLY
appreciate that info. Thanks!!
Problem 6. In the figure 1 the coil wound on the ferromagnetic bar moves with speed v with respect to permanent magnet pole N that gives the magnetic flux density B. The coil of N numbers of turns is closed through the load impedance Zi. a) Mark the direction of: We...
b) How does the magnitude of the induced current depend on the strength of the bar magnet? PHY290 c) If the secondary solenoid is in a circuit with resistance R, there will be an induced current, 12 = Discuss how the equations predict the direction of the current in the secondary coil depending on whether the current in the primary coil, 71, is increasing or decreasing. Is it increasing or d) Does this match your decreasing?) s this match your...
1) Induced emf in a coil depends on a) Relative motion of magnet b) Relative motion of coil c) Both d) None 2) When is passed through coil is there magnet a a (changing/unchanging) magnetic flux through the coil that induces an electromotive force(emf) in the coil; the incoming flux is (equal /not equal)to the outgoing flux. 3) While a magnet is moved toward the end of a solenoid, a voltage difference is induced between the two ends of the...
can you please show me how to do each of these thank
you!
