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 the tube. If the initial magnetic field in the solonoid is T and R/r=12.0, what maximum value of magnetic field can be achieved?

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?

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?

Neurons in our bodies carry weak currents that produce detectable magnetic fields. A technique called magnetoencephalography, or MEG, is used to study electrical activity in the brain using this concept. This technique is capable of detecting magnetic fields as weak as 1.0 ✕ 10−15 T. Model the neuron as a long wire carrying a current and find the current it must carry to produce a field of this magnitude at a distance of 5.4 cm from the neuron.

Write an overloaded procedure using c++ for approximating the value of cos(x), called approx_cos. This procedure should work as follows: A call such as approx_cos(double x, long N) should produce the Nth order Taylor approximation of the cosine function at the point x. You of course need the derive this Taylor expansion in order to implement it. A call such as approx_cos(double x) should approximate the value of the cosine function evaluated at the point x, to at least eight...

You can use either electric or magnetic fields to steer moving charges. Suppose you have a beam of electrons moving in the xdirection with speed 1.0×107 m/s, and you want them to turn 30° to their right in a distance of 1.00 cm.(a) [2 pts.] One way to turn the electrons is to run them between two charged plates that are 1.00 cm wide. There will be a uniform electric field between the plates. What direction does the electric field...

Very large forces are produced in joints when a person jumps from some height to the ground. a) Calculate the force exerted if a 96kg person jumps from a 0.6m high ledge and lands stiffly, compressing joint material 3.4cm as a result. (Be certain to include the weight of the person.) b) In practice the knees bend almost involuntarily to help extend the distance over which you stop. Calculate the force exerted if the stopping distance is 0.3m. c) Determine...

A randomized, double‑blind experiment studied whether magnetic fields applied over a painful area can reduce pain intensity. The subjects were 5050 volunteers with postpolio syndrome who reported muscular or arthritic pain. The pain level when pressing a painful area was graded subjectively on a scale from 00 to 1010 ; (where 00 is no pain, 1010 is maximum pain.) Patients were randomly assigned to wear either a magnetic device or a placebo device over the painful area for 4545 minutes....
