What is the definition of magnetic flux? What is Faraday's Law? Can you use it effectively to find the currents induced by changes in magnetic flux? How can it be verified experimentally using a field coil and a pickup coil? If you know how the magnetic field changes in time in a field coil, can you determine how the current induced in a pickup coil will change in time?

1. Faraday’s law of electromagnetic induction is a law that states that when the magnetic flux linking a circuit changes, an electromotive force is induced in the circuit proportional to the rate of change of the flux linkage. Please click the link: https://phet.colorado.edu/sims/html/faradays-law/latest/faradays-law_en.html And observe the fluctuation of induced current in the circuit by moving the magnet.

How do you imagine you can increase the magnet field from a magnet (Faraday's Law)?

Faraday's Law: What would you observe about the amplitude of an induced signal as the frequency varied? Describe whether the behavior is consistenent with Eq. 3 (Vo= w(Nd)A(Bo)cos(theta)). In particular what should your graph of amplitudes against frequencies look like according to Eq 3? In comparisons with the predictions of Eq 3, why would it be important to adjust the function generator to keep the amplitude of the B field the same at each frequency?

Very large magnetic fields can be produced using a procedure called flux compression. A metallic cylindrical tube of radius R is placed coaxially in a long solonoid of somewhat larger radius. The space between the tube and the solonoid is filled with a highly explosive material. When the explosive is set off, it collapses the tube to a cylinder of radius r<R. If the collapse happens very rapidly, induced current in the tube maintains the magnetic flux nearly constant inside...

Magnetic flux lines, by itself, is not very useful. You can’t see them. You can’t touch them. They can’t be detected by sensors. So, by themselves, they are not very useful. Yet, as a concept they very useful. But within a context, when they are changing in time, in the vicinity of other things (what things?) they are important. Explain where Magnetic Flux is useful, where it is important?
