    How Long Does It Take for a Falling Square Loop to Clear a Magnetic Field?

    Thanks @nrqed, I did have numerical values and eventually solved it numerically.

    How Long Does It Take for a Falling Square Loop to Clear a Magnetic Field?

    I should add that I took length of side to be s = a (rather than x as roam did). I also had used opposite signs for my z-axis values from roam (i.e., I took +ve z direction to be upward, so Fmag was +ve and Fg -ve) so have an exponential with a positive argument. And I had called my notational...

    How Long Does It Take for a Falling Square Loop to Clear a Magnetic Field?

    Almost a year later and I have this exact same problem and am stuck in the same spot. Did you ever work your way past that point @roam?

    What SciFi universe would you live in?

    Futurama and it's not even close. It's like all the best bits of all the best worlds. But better.

    Safest region on Earth from natural disasters

    I've always thought levitation is a wildly underappreciated skill and should be taught in schools. In a nice gentle hover 50-70ft off the ground one is safe from pretty much anything except peregrine falcon attack, and those can easily be bought off as long as one remembers to pack a satchel...

    Orbit of Geostationary Satellites

    Ok, I'm with you now, sorry it took me two tries, mind's a little numb at the moment. Your advice is much appreciated, I'll have another go with it in mind.

    Orbit of Geostationary Satellites

    Thanks for the prompt reply Simon but I'm not sure I follow. Haven't I covered the angular velocities/frequencies aspect in the second paragraph of my first post? Or are you saying I would be better to use the term "observer" rather than "the point on the planetary surface" to streamline it? As...

    Orbit of Geostationary Satellites

    When I researched the answer I mostly found responses which leaned toward Kepler's 3rd Law, but I can't get my head around how the 3rd law can be used to describe an orbit with a radius which must be necessarily be fixed at the centre of a planet. Other answers I found talked about how an...

    Orbit of Geostationary Satellites

    Hi all, I feel like I have the answer, or am at least in the ballpark, but I'm not confident in this area and so I also feel like there should be a more concise, or "beautiful" way to express it. Am I missing something? 1. Homework Statement Explain why the orbit of a geostationary satellite...

    Graduate Conservation of Energy in Mechanics for Point Mass

    Thanks Matteo, that's somewhat familiar but I'm so rusty on this stuff it's not funny.

    What Makes Physics So Fascinating?

    I like physics because it's the branch of the sciences which provides me the most awe.

    Graduate Conservation of Energy in Mechanics for Point Mass

    Reading "Atmospheric Thermodynamics" I'm stumped almost as soon as I've started. I've probably bitten off more than I can chew and this also might even be more of a math question than a physics one but where I'm stuck is where they "simplify" from: mv . dv/dt = -mgv . ez (where ez is a unit...

    What degree is this undergrad student working towards in New Zealand?

    Cheers mate (as we say when we're not saying "kia ora bro"), I'm always happy to hear folks had a happy time here. I'm only stage 2 so not 100% on my major yet but leaning upward. Toward The Cosmos.

    What degree is this undergrad student working towards in New Zealand?

    Hi guys, I'm an undergrad student from Auckland, New Zealand, picking up a degree this year that I started but never finished in the late 90s. Better late than never. I hope.
