Understanding Magnetic Fields: Compass Direction in a Bar Magnet

AI Thread Summary
When a compass is placed inside a bar magnet, the north end of the compass will point towards the bar magnet's north pole, following the direction of the magnetic field lines, which run from south to north. The compass aligns with the tangent to the magnetic field at its location. Historically, the north pole of a magnet was defined by its attraction to the Earth's geographic north, which is actually a magnetic south pole. This distinction highlights the complexity of magnetic terminology. Understanding these principles is crucial for grasping the behavior of magnetic fields.

Homework Statement



If a compass was placed inside a bar magnet which way would north point.

Homework Equations





The Attempt at a Solution


It seems when you put a compass around a bar magnet it points in the direction of the tangent to the magnetic field line at that location. Inside a bar magnet the magnetic field lines run from south to north so i believe the compass "N" will point to the north pole of the bar magnet

Historically, a magnet's north pole was taken to be the end of the magnet that is attracted to the direction of the north geographic pole. Of course today we understand that this makes the Earth's north actually a south magnetic pole!
 
Not sure if that was suppose to help?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
