So i'm trying to build some electromagnets and i have some questions regarding how to power them. Imagine that i have a battery of 6 Volts and a coil with x gauge with y meters of wire that will equal 1 Ohm of resistance. So if i want to run it with 1 Amp of current i just put one 5 Ohm's resistor in series and i get the current i want. So far so good right? Here's my confusion. If instead of a coil i wanted to power leds that had foward voltage of lets say 2. I could only power 3 of them. No matter the current im putting in (right?). So in the coil case, instead of the 5 Ohm resistor what if i put 5 coils of 1 Ohm? i would still be running 1 Amp but instead i would be powering 6 coils instead of just 1 (?!) Isn't there something that limits the number coils i can use just like the LEDS case? i think i'm missing something very basic here thank you for your time, i'm still very new to electronics.
