Of course you can't predict the future, though you can come to an estimation of it, a probability of it if you will. Certain fields that involve specialists, people who have knowledge in that particular field that is uncommon, there will always be a demand for them. Buggy whips are a completely...

I'm wondering what are some 'niche jobs' or niche markets for Electrical Engineers? The kind of jobs that will always be in demand. I've heard that RF Engineers are always in demand, that there's a short supply and such...but what other fields are there within Electrical Engineering?

Thanks for that..kinda makes more sense.

Hmm I see then. Can my system still be described by Faraday's law of induction, or Ampere-Maxwell law, at least superficially?

Maxwell's equations describe electric and magnetic fields, which in turn give rise to electric and magnetic forces; why else are they described as vectors, or vector fields? Plus the Lorentz Force is related to the hall effect, and it's also related to Faraday's law of induction. The Hall...

I have some copper enamel wire, winded up into something of a circle/ellipse, with about 20 turns, and the purpose for it is to give me a decent magnetic field (which it does) using a DC source. The magnetic field is picked up by a hall effect sensor on a nearby circuit, which is connected to...

Thanks for that.

Hmm perhaps you're right. I just thought that the wire with the better conductivity would be 'best', which in this case is the enamel copper.

Yes I'm familiar with all of that. This is for a 3rd year electromagnetism course. We have the necessary impedance in place. Just wondering which type of wire is best suited for a magnetic field? I think it's the enamel copper, but just want to confirm.

I'm looking at getting a lengthy piece of wire, looping it around into either a circle or an ellipse and running a current through it to get a magnetic field, however I'm unsure what type of wire to go for? There's enamel copper wire and the standard aluminum wire. Which one will give me the...

^^There's a store in my city that has a kit project where you build you own multimeter, might look into it. Thanks for the link berkeman.

I'm a second year Electrical Engineering student and I figured it's about time I purchase my own digital multimeter and build some stuff :) So I'm just wondering which type would be best suitable for someone in my position? Keep in mind that my budget is somewhere around the $20 mark, plus...

^^You're right it doesn't make sense, and it isn't right..I thought that was the limit of sin(x) as x goes to infinity but I forgot that it's actually not defined. But taking that 'reasoning' solved my problem with finding a0. As for the power of the signal, I figured it out (well I found the...

Ok I figured out a0...i just forgot that a zero in the denominator means that the value goes to infinitiy, and the sin of infinity goes to 1.. That leaves the total power then?

Homework Statement We're given this 'interactive page' that gives us the values, so T=2.8066, W=0.9542 and A=8.5988 and then told to find a0, b0, a1, b1, a3, b3, Total Power and 3rd harmonic power. Homework Equations Cn given above and: a0=1/T \int s(t) dt integrating from 0 to T. Also...
