Web5 mei 2015 · As the magnet continues to fall, and enters the coil, more of its magnetic field is threading imaginary disks in the coil, so as it moves the time rate of change of total flux increases, so the EMF goes up. Note that the field lines above and below the bar … Web8 aug. 2024 · My understanding is this: When you drop a magnet through a copper coil the acceleration is reduced as it enters (and leaves) the coil as these are the points where the flux linkage change occurs, and so EMF will be induced. This EMF will oppose the direction of motion (Lenz's Law) and thus it will slow the magnet. Hopefully I'm right so far. supra kimweb

So, for each imaginary disk inside your coil we get some EMF as the flux through that disk changes in time. Now think about the bar magnet's descent. Suppose we drop it starting way above the entrance to the coil. barberia bannerWebIt makes a difference if you think about it. If the magnet is travelling at 0.1 m/s it will cut 3 (just a random number) coils in the solenoid. Since its accelerating it is now at a speed of, lets say, 0.3 m/s. Therefore, in one second it will travel further than previously and hence cut MORE coils in the same time. suprakolorWebAnswer (1 of 3): The coil, if it competes a circuit, will have a current induced into it. The flowing current will, in turn have its own magnetic field. Lenz’s law describes this.
