So basically, those two circles drawn around the magnet could be in either direction, as long as they are in different directions relative to each other. If the top one was going around ← this way then the bottom one would be going around →this way. But it would be OK if the top one was drawn...
Thanks for your answers, they were very understandable! :)
You mentioned they are always going from North pole to South pole; however, above they go in a complete circle around the magnet. Doesn't this mean that they go from North pole to South pole in half a circle and then from South pole to...
Homework Statement
Currently I am taking a course that teaches half the material and let's you figure out/ guess the other half. I have been pretty good at succeeding in this so far, but this one has me stumped. It is on my practice test.
What in the world does this diagram mean?Homework...
Sorry,
I am solving for current in the primary coil (Ip). I didn't know which equation was correct, because both could be used and they didn't come up with the same answer. I have already found that Vs = 40 volts.
Homework Statement
A 4.0 Watt toy motor is connected to a secondary circuit of a transformer with 60 loops and a current of 0.10 A. The primary voltage is 120 V Homework Equations
Vp / Vs = Ip / Is
Ip = Pp / Vp[/B]The Attempt at a Solution
1. [/B]Vp / Vs = Ip / Is
120 V / 40...
Thanks guys, I think I will submit it like this.
Yes, I'm sure this is correct. It's really a pain. I am doing Functions with them as well and my Dad, who had been a calculus teacher for the past 20 years, said they teach Functions in a very strange way too.
What do you mean by 'the lines of flux'. Or which lines on the diagram are they? This is what my online textbook did as an example. Did I do it right and they are just teaching it strangely?
