Magnetic coil to stop a cylinder from falling down

Please login with a confirmed email address before reporting spam

Hi there!

I'm new to Comsol and could use some help. I'm exploring the possibility to control a iron cylinder with the help of a copper coil. But I'm to new to Comsol to understand how I'm suppose to do all the steps.

I've done a coil of copper, fixed it in space. I've done a cylinder and fixed it so it can only fall straight down. But how generate a electromagnetic field in the coil?
