| Feb 7 at 16:21 | comment | added | Farcher | The force does not depend on distance rather it depends on the person/entity pushing the magnet. Pushing harder will mean that the magnet moves faster, a larger emf/current is produced, ie more work done per second means more heat is produced per second. | |
| Feb 7 at 15:15 | comment | added | Pumpkin_Star | But is my understanding in the above two comments, correct? especially the first one? Or have I still got it wrong? | |
| Feb 7 at 14:20 | comment | added | Farcher | There is a balance between the rate of work being done moving the magnet and the rate at which heat energy is generated, facilitated by electromagnet induction. | |
| Feb 7 at 14:04 | comment | added | Pumpkin_Star | Is it like electrostatics? As in, the force is always there but as you go nearer the force increases and the KE gets converted into PE? If so, then over here, is the KE being converted to both PE and the current? | |
| Feb 7 at 12:17 | comment | added | Farcher | @Pumpkin_Star - Whoever or whatever starts pushing the magnet into the coil has to do work so that is the source of the energy supplied to the coil & magnet system. The movement of the magnet into the coil induces an emf which in turn produces the electric current - this is the "electrical energy" bit. The electric current passing around the circuit which has resistance produces heat. | |
| Feb 7 at 11:55 | comment | added | Pumpkin_Star | The bar magnet first induced the electrical current in the coil, after which the coil repelled the bar magnet and reduced its kinetic energy right? But who provided the electrical energy in the first place? I am very sorry if this comes across as a silly question. | |
