At 75°C (where solenoids often operate), R rises to 2.43 Ω. Aim for a coil resistance that actually limits current (~6-8 Ω for 12 V, giving some headroom). In that case you have to dump all that stored energy safely. For MRI scanners, you’re talking about big superconducting coils—no iron, just high turn count at 4 K—so you make fields several Tesla in size. For most electrical steel, this tapering off begins at about 1.5 T, and by 2.1 T you’re nearly saturated—the rest of your power just makes heat. The field drops off more near the ends if the coil isn’t at least 10 times longer than it is wide, which is common if you’re tight for space or building short, fat coils for compact devices. Adjust current, turn count, and coil length to see live field calculations and how the solenoid's field changes as you modify each parameter. https://guyads.com/author/scarlettddr/
