Request: EMily. Faith in Lenz' Law by Scisyhp Request: EMily. Faith in Lenz' Law by Scisyhp
Hey there everyone. First picture of the summer, and I just finished it this morning. And I hope everyone in the US had a fantastic 4th of July! My summer's going alright, to be honest. I've been working with studying for the qualification exam, doing some research for nuclear physics, getting headaches from the weather, and doing the time honored tradition of replaying the Jak and Daxter trilogy every summer. There are a lot more details in there, but I want to get to the drawing!

This was a request for Erasota, who I cannot thank enough for being patient with me ever since the summer started. The request was to have the FoN girls drawn... using their dresses as parachutes. XD Well, I couldn't just straight up do it like that, since I always aim to have my drawings related to physics. So what I thought was something along the lines of electromagnetic levitation for EMily. So then I thought, what if she could make herself into a magnetic dipole? EMily, for those of you who don't know, is my personification of the electromagnetic force. So if you have any objections over her power to turn an insulating dielectric into a magnet, don't be a party pooper. She's the embodiment of the EM force in this case, so she can turn herself into a magnetic dipole (although for those of you who know me from WAOA, that's a different story). Here's the rest of the physics that's happening: EMily is now a falling dipole with her magnetic north pointing straight down. Below her is a conducting wire around a metal core, which sees in increase in magnetic flux. Magnetic flux or "flow" refers to how much of a magnetic field is flowing through an area. Lenz' Law states that a change in magnetic flux through a conducting loop makes the loop create a current that subsequently will oppose the change. In layman's terms, I'll refer to Griffith's who says: "Nature abhors changes in magnetic flux." The inductor creates an opposing magnetic field, which then acts on the strangely feminine dipole that resides above it, making it slow down.

The equation on the left is the integral form of Maxwell's 2nd law, which states that a change in magnetic flux (on the RHS), creates an electric field (on the LHS). And that is the electric field that's creating the current in the loop in the picture. The equation on the right is the equation for the force of a magnetic field on a magnetic dipole.

I wanted to take some steps above what I usually do for shading, because I really wanted the dress, and especially the folds of said dress, to pop out this time. I also think that this is a far stronger drawing for EMily than the last summer drawing I had her in. Mostly because I wanted to put more physics in it. The drawing was mostly celebratory, but I knew I could have done better.

Other than that, I might do another drawing by the end of August, but I'm getting close to the qualification exam. And while I feel fairly confident about it, I still want to keep up my training.

I hope your summer is a blast! Enjoy!

I like your art, it hard to find science personification
Just keep go on

Wow, I love this. ^^ EMily looks really pretty in this.

I also really like how you apply physics into your art and having a reason for everything in it. =)

Thank you so much for drawing this and I'll be looking forward to the others. ^^

Thank you very much!

I always have to think about their character and how they're related to physical principles whenever I draw. It's part of the reason how the characters came to be in the first place. :)

And you're most welcome!
