Does a solenoid get warm with inductance?

[BenTHS]

Hi,

I'm wondering if a solenoid is only hot by copper resistance or in addition with the inductance produced into the coil too ?

Another small question : in the sofware Femm there is a computing result parameter called "voltage drop"; does it means you need ( at least ) x volt to get the magnetic field or is it necessary to use much higher voltage ?
In Femm you indicate the diameter and kind of wire, the intensity or the number of turn but not the voltage of the power supply; I'm surprised ?Thanks by advance

Only resistance heats up with $I^2R$ losses. Pure L and puree C don't. But in real life and nothing is pure.

If the coil core is not of a ferromagnetic material-and no ferromagnetic material is in vicinity then no losses are expected. Since we are speaking about L and reactive power it is about a.c. current. In a.c. a magnetic core presents eddy-current and hysteresis losses. These losses could heat the core and from here the copper could be heated also. See-for instance:

I agree with you, in order to calculate the Fem one needs only L and I [Fem=LdI/dt].The voltage is present in the entire supplied circuit. However, the wire insulation has to be chosen according the presumable voltage.
