Web10 aug. 2015 · The "induced B-field" is a fictional construct which makes it easier to figure out the direction of the current. But my method is actually 1. Outstretching the four fingers in the direction of B-field (the trick is to do this at a place where the B-field lines are perpendicular to the segment of the loop) 2. Web28 jun. 2024 · First, a magnetic field is generated when current flows. A simple wire carries no current. So, unless the wire is part of an active circuit (e.g. a lamp that is turned on) there will be no magnetic field. Even if there is a current flowing, it will be a 50 Hz current, so the current and the magnetic field reverse 50 times per second.
