In case you have any doubts or you did not understand any step
please feel free to ask your doubts in the comments section. I
would be happy to clarify it.
Could you illustrate the followign?
1. magnetic vector potential A,
2. magnetic flux density B,
3. and current density j
4. Electric field entisity E
5. Electric Potential V
When a DC current passes through the coil, it will produce a
magnetic flux around the coil. Is this the reason why the coil get
heated? Because the magnetic flux will be stable after all as DC
current does not oscillate?
Use tables and cash flow diagram: The equivalent
annual worth of an increasing arithmetic gradient is $135,300. If
the cash flow in year 1 is $35,000 and the gradient amount is
$19,000, what is the value of n at an interest rate of 10% per
year?
Draw a cash flow diagram for a cash flow that starts at $1,000
at the end of the first month and increases by $100 each month
after that in perpetuity with an interest rate of 21% annual
compounded monthly (Draw at least the first 5 months). What is the
present value of this cash flow?
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?
Questions:
Creating a diagram and written explanation, explain the
magnetic field direction and strength around a bar magnet, and an
electromagnet.
Explain the similarities and differences of a bar magnet
and an electromagnet.
Identify the characteristics of electromagnets that are
variable (can be changed) and what effects each variable has on the
magnetic field’s strength and direction
Draw an AS/AD diagram to illustrate a decrease in dollar
value in the US economy . Clearly label axes and the current
position of AS & AD relative to full employment RGDP....also
indicate any shifts that would occur if the exchange rate of the $
rose sharply against other major currencies
Suppose the economy is in a long-run equilibrium.
a. Draw a diagram to illustrate the state of the economy. Be sure
to show aggregate demand, short run aggregate supply, and long-run
aggregate supply.
b. Now suppose that a stock market crash causes aggregate demand to
fall. Use your diagram to show what happens to output and the price
level in the short run. What happens to the unemployment
rate?
c. Use the sticky-wage theory of aggregate supply to explain what...
Create a diagram of a current-carrying wire in a magnetic field.
Draw the field lines and explain how the direction of force acting
on the wire is determined.
#- Create a sketch of the experiment Michael Faraday performed,
label all the parts, and write a brief explanation of how motion is
created.

Online Recruiting System (website)
1) The Online Interview System: The search committee usually
selects 3 to 5 candidates for a Skype interview. When the search
committee starts a Skype interview, they connect their web browsers
to an interview module developed by the company’s IT team (we call
this type of software as home-developed software). The interview
module then connects to Skype....
