That sounds brilliant. First, she's okay with kiddie stuff like waving fridge magnets in front of her eyes, then she steps it up to always having one on all the time.
Soon, the kiddie stuff isn't enough and she starts hitting rare earth magnets. Not very hard, just briefly close enough that she can feel it in her EM shielding. Without meaning to, she slowly increases in frequency and length of exposure as she starts to feel the cravings set in.
This is when her friends start to notice, and she laughs it off with a few jokes about ancient tube TVs and rainbows, but she knows that they're onto her and she can't do it in the house any more.
In her desperation to move her "hobby" away from her friends, she stumbles across several other hobbyists who introduce her to the joys of electromagnets. A wonderful world of shield overloading awaits her, but she has to chip in more and more for the electric bill at the place she goes to, since scrubs keep chickening out and leaving more and more of the bill to her when they stop coming.
It gets harder and harder to scrape Edison bill money together to support her hobby. Since data reconstruction is time consuming, she can't hold down a job that requires virus scanning. She'd pass the virus test no problem, but Magnetizers have a bad rep amongst AIs and they'd spot the signs immediately if she didn't finish reconstruction before the test started. Her friends were okay with lending a few bucks here and there, but $1500 every month is a lot to bum off a group of friends. They'd talk. They'd put 2 and 2 together and figure out that the full time job they think she has is really 15 hours a week plus magnet time.
She almost quit cold turkey the first time she saw a guy fuck up his BIOS. One second, he was giggling about new frontiers, and the next he fell over putting out error beeps. She was still reconstructing her audio files when they dragged him out, but she swore the beeps cut off before they got out of earshot. She never saw him again, but apparently he got better, because he paid the next few months Edison bill as a going away present. Besides, he only had problems because he tampered with his Core casing, and she's not stupid enough to crack it open. It's enough to just rub it on the outside after opening up her chassis.
At some point, she realizes that she's wasting a lot of time on data reconstruction. it's going to get fuzzed again anyway, so why not just let the low priority files stay that way a little longer so that she can get an extra turn on the mag? She hardly talks to her friends any more because of money issues, so there's a lot of memory that can be left for next time. She doesn't go to work any more, so there's another batch for the low priority list. Leg gyroscopic alignment? That seems like it would be important, but she marked it as low priority last time, so it must be this time too.
Hmm…Visual numeric recognition seems to be off. Is that a 10 or a 100? No, definitely a 10, but she'll definitely skip her turn next time so she can address thi$) '&589!:%568
