what determines the amp draw of a solenoid? first i thought it would be determined by the movement caused by the magnetic field but here it look like it is still drawing the same current when de core stops moving. Is it the core being magnetised? or just the constant power needed to keep the magnetic field intact? any thoughts or explanation would help a lot
It's basically an inductor so current will start low then quickly rise to steady state where it's limited by wire resistance, AC works differently though but isn't what's used here.
