Hey guys. Made two animations with FEMM, it shows the magnetic field lines of a fully encapsulated coil and a coil with only end pieces. The projectile moves through the coil, and the magnetic field intensity and distribution can be seen changing.
I imagine these can be of use for beginners who want to get a better idea of how the magnetic field behaves, and how flux enhancement acts. But I am not sure where I should put them so most people may benefit from them. Any ideas?
Also, there seems to be some problems with uploading the second gif, so only one is shown here.

Very, very cool! Dontcha just love how it shows the projectile saturates before the field pieces? This means you can improve energy transfer efficiency by using a thicker projectile (or by lowering the applied energy).
I hope you find a good spot to publish the images. Does Picasa Web support animated GIFs?

Cheers, Barry
