I'm looking for some examples/ideas on how to control the current to an electromagnet based on the height something is levitating above it. Schematics would be nice, but even any ideas/sensor recommendations would be appreciated. or any similar application, I've seen something does using an...

Anyone else? having weird problems with the magnetic fields around the nails, and better ideas for cores?

I'm building a fairly simple maglev demonstration, I am not currently worried about propolsion since more is required there then is necessary for this. Im looking for recommendations on designs, websites etc where you've seen models done...Not ones with all permant magnets, and not sites...

BTW I am trying to find the angle...and the 100m/s is the Hypot. componet of the velocity

Im given the initial speed (100m/s) of an object launched at an unkown angle, it needs to just barely go over an object 5m away 2m high. Ive made several attempts at this, all of which ending up in the trash my most recent try is y=(Vy + (1/2)(-9.8)(t^2) t = 5/(Vx) Then used Vx^2 =...

I think you misunderstood the question, i need to know how long he accelerates, in order to finish in 3 mins, if you read the question more closely youll realize its not as simple as i thought, i immediatly did what you suggested, until somone else pointed out the other details

A runner hopes to compleate the 10,000m run in less than 30.0min. After running at a constant speed for exactly 27.0min there are still 1100m to go. The runner must then accelerate at 0.20 m/s^2 for how many seconds in order to achieve the desired time. Ill briefly summarize what i tryed...
