I have a question regarding how a Yagi type antenna radiating its energy with respect to faithfully replicating the original signal. So let's say you have a FM modulating signal, F(x(t)) whereas x(t) is the data, and F(t) is the carrier, so basically x(t) would FM modulate the carrier F(x)...

I have to say that is a very odd question. What is it that you're trying to pull? By what mechanism -- I assume some type of electromagnetic force but could you be more specific? Based on your description, I mean it could be anything. Sorry if I am being a bit blunt. I am not quite as...

oops, sorry, I was trying to answer a different question. I mean the OP could be more specific by saying he is trying to calculate the electromagnetic force induced by using a solenoid (at least I think that is the intent of the question). I thought he was asking about how fast a car with 1.5T...

Hm... I thought the OP was asking how much his 1.5Ton object can be "pull" by using a 48V pack. I am not sure what you referred to in your post such as electromagnetic and resistive losses had anything to do with my post? I was simply trying to refer how much his 1.5Ton can be pulled by the...

Your question may lack some specifics but in general, the "pull" that you mention I take that it means "power" or how much work can be done given a specific time. Battery power can be measured in how much current it can discharge. For example, if the 48V battery can discharge 10A at any given...

I mean using a program so it can be automated?

For non-text materials such as online documents such as .pdf or .doc, how do you read the contents?

I was having dinner with a friend of mine a long time ago and we were discussing religion, and then he said well science is like a religion too. I told him, although not directly disagreeing, that in science people are willing to change if a better theory comes along. I read the book "The...

It seems like a lot of confusions arise from not agreeing on the terminology. I am still not sure what you're referring to when you're using the term "electromagnet". So I'll continue to illustrate based on what I know of the Maxwell equation and some basic circuitry. Think of this situation...

OK, I see now what he was asking. Let's look at a simpler example. If we have a constant carrying current or a DC current, there is obviously a magnetic force proportional to the strength of the current, but the magnetic would be a constant therefore dB/dt = 0. So even if you place this DC...

Actually I am still not quite sure what you're asking. Your usage of the terms "electromagnet" and "ring current" might be a git general. I was wondering if you could be more specific

Thanks for the explanation. I have a scenario in which it's not clear whether the force is a pure magnetic force or pure electric force I hope maybe you could explain. For example, I have a current carry wire in the y-direction going from bottom to top. A charge Q1 is moving also in the...

I am not quite sure what you meant by this? Do you mean if you rotate a wire, will it create a magnetic field?

I listen to rock music and usually in the musical mix, the drum is placed at the center/back of the soundstage, the vocal is at the center/front, and other instruments like guitar, piano are either are the left or right and slightly up front. So this gives a nice weight to the soundstage with...

I guess this picture explains how you can reconcile the chemical vs. equation point of view. A link is also provided. For a rigorous treatment, I would recommend the online course from nanohub at Purdue university...
