Electromagnetism exercise

Reply Tue 17 Nov, 2020 06:24 am
Hey guys,

This is my first time here, so I ask you to redirect me if I commit any mistakes.
Ok, so I'm struggling with electromagnetism a lot. I'm trying to do an exercise but it's really hard for me. I would appreciate some help if you can.

'Consider a very long conductive wire with an electric current running through it at y-axis. Next to the wire, there is a square metallic loop (a * a) that moves with constant speed in the x direction. Determine the force required to keep the loop moving at a uniform speed u = ux' (x' is the unit vector in direction x).'

Thanks for any help and sorry for any mistakes.
