Observing Electric and Magnetic Field Lines Around a Current Carrying Wire

Physics Asked by GISEnthu on March 28, 2021

Referring to the idea of using grass seeds for observing electric field near current carrying wires from the following article,
https://www.ifi.unicamp.br/~assis/Found-Phys-V29-p729-753(1999).pdf

grass seeds for electric field

I am wondering how can we visualize both electric field and magnetic field simultaneously using both grass seeds and iron fillings around a current carrying wire. Since they will be perpendicular to each other will it be possible to practically execute this idea?
