... 3d.i. A given current will always produce a weaker-than-expected magnetic field because the solenoid is not an ideal solenoid. There will always be an “edge effect” unless the solenoid is infinitely long. 3d.ii. The absence of a resistor leads quickly to a very high current which would likely burn-o ...
