The magnetic field in a solenoid of length $L$ around an iron core with $N$ turns is given by: $$ B = \mu \frac{NI}{L}.$$. Assuming some Ohm's law type of resistance in the wire we can replace $I$ with $V/R$ to get $$ B = \mu \frac{NV}{LR}.$$. So the magnetic field strength increases linearly with both the number of turns and the voltage. The resistance of a wire is given by. $$ R = \rho \frac{l}{A}, $$.(where $\rho$ is some material property of the wire, $A$ is the cross sectional area and $l$ is the length) so that $LR = \rho Ll/A$ and.ssuming some Ohm's law type of resistance in the wire we can replace $I$ with $V/R$ to get $$ B = \mu \frac{NV}{LR}. $$.

The Bureau of Labor Statistics reports that as of May 2008 licensed vocational nurses earned a median annual salary of $39,300. The middle 50 percent of LVNs earned between $33,360 and $46,710. According to Health Careers Center, the average annual salary for an RN with an associate degree is $50,200.The average salary ranges from $41,300 to $58,400. Note that this is clearly on the low range of what RNs earn, as RNs with a BSN and other specialized training earn significantly higher salaries.verage Salary for an RN with Associate Degree. According to Health Careers Center, the average annual salary for an RN with an associate degree is $50,200.
