Adding a resistor in series will increase the impedance, but I'm not sure it will give you the results you want. Impedance is not the same as resistance.

[u]Resistance is not frequency-dependant.[/u] The inductance of a coil causes it to have a higher impedance at higher frequencies.

Another important factor is the number of turns, which directly affects how much current is induced. Using resistance instead of inductance to arrive at a particular impedance value, means you have fewer turns in the coil to interact with the magnetic field.

Current is induced when magnetic lines of flux move across the wires in the coil. A resistor doesn't have this property.
