If a needle is moved away from north and then, released, what will happen?
The answer is that "magnetic dipoles twist to align with the magnetic field",
My question is: does not having a magnetic dipole moment mean that a current must be running through the compass needle since the magnetic dipole moment is produced by a current running through a wire?

1. The stack of magnets works as one big bar magnet. Do the poles change when you divide the magnet into pieces? 2. In step 3 of the experiment, do both sides of the magnet attract the metal surface? Explain how a single magnet can repel the rest of the stack, but still stick to the other surface. 3. How does the magnet attract something that is originally non?magnetic? 1. Describe the direction of the compass needle as you moved...

Results Neatly write up your calculations for H and B, either typewritten or neatly on engineering paper 1.1 Part A You should have identified a null point along the axis of the magnet where the magnetic fields due to the Earth and magnet cancel. Measure the distance from the null point to the center of your magnet (this will be our dis- tance r) Now BE and Bm are oppositely directed, and since it's a North...

Here's a cool example: Permanent magnets. If B are produced by currents, then what's up with permanent magnets? You don't have to plug them in, they just work. What's the current? One idea is that it could be the e' orbiting the nucleus. A charge moving in a circular loop is a sort of current. (You'll calculate this in Problem 30.6) Let's estimate the speed of the e' using Newton's Laws: the only force is the Coulombo attraction, and we'll...

power source, establish a current in the swing. We are interested only in the lower section (seat) of the swing here. You will need to make sure you understand the interactions so that you can determine the direction of the current through the swing's "seat". There is a very strong magnet with the North pole on top and the South pole underneath the current carrying wire. Your charge here is to observe the effect on the swing, i.e. the direction...

Read the article below and in your own words, (1-2 sentences) what is the "true direction" or right way to interpret nature, according to Bacon? True Directions Concerning the Interpretation of Nature (1620) Francis Bacon Those who have taken it on themselves to lay down the law of nature as something that has already been discovered and understood, whether they have spoken in simple confidence or in a spirit of professional posturing, have done great harm to philosophy and the...
