Will the "south" pole rotate up to the "north" pole, causing the system as a whole to rotate?
It is my understanding (and it has been awhile since magnetics in college) that it would rotate toward "north" - like a compass. But for sure I would like to be able to control the direction of rotation...A.T. said:Why not the other way around?
Are the vertical and horizontal bars free to rotate relative to each other, like the compass needle can rotate relative the Earth? If, yes do they have the same mass ratio as the a compass needle and the Earth?pbhuter said:like a compass
pbhuter said:This is operating in a frictionless environment. Each bar is the same mass, and like I said there are four making a complete cross. I am trying to see if the whole thing will start rotating about the center as the "south pole" is attracted to the "north pole".
No. An internal force cannot cause a net torque.pbhuter said:causing the system as a whole to rotate?
Magnetic rotation refers to the phenomenon where the Earth's magnetic field changes over time, causing the magnetic poles to shift and move.
No, the Earth's magnetic field is constantly changing, but it does not completely reverse. The magnetic poles may shift, but they will always remain opposite from each other.
The Earth's magnetic field has changed many times in its history, with an average of every 200,000 to 300,000 years. However, the last reversal occurred about 780,000 years ago.
Magnetic rotation is a natural process and it is influenced by the movement of molten iron in the Earth's outer core. Human activities do not have a significant impact on magnetic rotation.
The shifting of the Earth's magnetic poles does not have a direct impact on our daily lives. However, it can affect navigation systems and animal migration patterns that rely on the Earth's magnetic field.
