    What sort of EM field is produced in an induction heater?

    Actually, I think there might have been a misunderstanding. My original question was how I could go about measuring the coil's magnetic field, but that's not an actual constant, since it'd constantly change as different objects are brought into the coil, and change as they heat up, too. (For...

    What sort of EM field is produced in an induction heater?

    So. Field strength in Tesla * Area of coil * 2 * 3.14 * Frequency = Volts per turn per Tesla therefore Peak field strength in tesla = V/turn / (Area of coil * 2 * 3.14 * frequency) But there's one thing, we don't exactly know the field strength that would be inside the induction heater. Also...

    What sort of EM field is produced in an induction heater?

    Well. Your idea is nice, but 200khz is only an approximation of the real frequency. The switches are a full-bridge of FGH60N60SMD IGBTs, connected in this configuration (with some added protection for the bridge) You should also ignore the values on the capacitor and the inductor, as I just...

    What sort of EM field is produced in an induction heater?

    So. Tesla = Volts / (Turns * 2(3,14*frequency)) If so, what does area even have to do with that? You just need to know the turns. Also, please refer to my previous post. I think I'd agree with you about the magnetoresistive sensors. Hall-effect sensors were what I was thinking of using so far...

    What sort of EM field is produced in an induction heater?

    Well, the ADC on the uC is said on the datasheet to be 2.4 million-samples-per-second each, with 3 in-total on the controller, which means a total of 7.2 million samples per second if we interleave them all. That means I can measure 1.2 Mhz with 1, and 3.6 Mhz with all 3. Considering the highest...

    What sort of EM field is produced in an induction heater?

    Actually, it's an STM32F7 Discovery board, which does have Arduino headers, which has a 12-bit ADC, which is higher than Arduino. I believe it would be fast enough to measure the AC waveform, considering the microprocessor has more than 400 MIPs of performance. Now, your equation. Shouldn't...

    What sort of EM field is produced in an induction heater?

    So basically currents would be induced into the wire, which I would connect to an analog pin, and measure. I realized I can do that, but how can I actually turn the voltage induced in said wire into units? Gauss? A/m? V/m?

    What sort of EM field is produced in an induction heater?

    What sort of EM field is produced in an induction heater? And how to measure it? That's it, basically. Assuming an induction heater is running on 200khz, and consuming about 3000 watts, how would I go about measuring the magnetic field produced in its coil? Now, I'm rather confused about all...

    Layden jar questions? And some static electricity questions.?

    Uh. okay. but how could i charge it from a tv? And please answer the other questions :) Your answer is really appreciated :D

    Layden jar questions? And some static electricity questions.?

    Layden jar questions? :) And some static electricity questions.?? Hello. I'm making a layden jar and i am kinda changing some details in it. and i want to ask if those will affect anything in the performance and if it's shocks can be lethal.. http://postimage.org/image/s9xqthylt/...
