| Nov 9 at 10:22 | comment | added | Sher | I still don't get which area A are you talking about. Sure moving the wire from outside will change flux through A, but what if the wire is moved slightly inside the field? Could you perhaps link an animation or drawing that shows what you are saying. | |
| Oct 7 at 17:57 | comment | added | trula | We can' continue in comments, so I stop . moving the wire parallel to B does not bring more field lines in A. | |
| Oct 7 at 15:22 | comment | added | Sher | Yes but that area changes even when we move the wire parallel to the field. Why isn't there any emf in that case? | |
| Oct 6 at 15:08 | comment | added | trula | The area of the loop with ire and voltmeter. Imagin the wire outside the field, then entering and more and more of the field in A. | |
| Oct 6 at 14:29 | comment | added | Sher | I have added a rough sketch. The green portion represents that part of the wire that is inside the field (ignoring fringing field) Now can you please explain what area A are you talking about? | |
| Oct 6 at 10:10 | comment | added | trula | Upwards does not say in what direction relative to B you move. so give a sketch or a good description of your experiment. | |
| Oct 6 at 9:45 | comment | added | Sher | I don't think I understand how that happens when wire is moved upwards. Also by that logic, A changes when the wire is moved parallel to field but we certainly don't see any current or emf in this case | |
| Oct 4 at 17:48 | comment | added | trula | If you move the wire A changes. | |
| Oct 4 at 8:25 | comment | added | Sher | Does the A change even when the wires are completely regid? | |
| Aug 31 at 14:25 | comment | added | trula | if you have the closed loop with the Voltmeter, moving the wire changes A. | |
| Aug 31 at 4:46 | comment | added | Sher | I was just asking because my textbook claims it's EMI. Also, how does attaching a closed loop make it EMI? | |
| Aug 26 at 17:12 | comment | added | trula | Which scenario with or without a closed loop. Without its not usually called induction, but it's not forbidden. Why ask just for names for something you know happens? | |
| Aug 26 at 12:59 | comment | added | Sher | So... Is this electromagnetic induction or not? | |
