Paleomagnetic dating utilizes records of "how things were" in a given area across time in the past as a basis for comparison to an unknown sample in order to date it. A link is provided to the Wikipedia article on paleomagnetism, which is the basis for paleomagnetic dating.
No, a static magnetic field cannot do positive work on charged particles. Magnetic fields can only do work on moving charged particles by changing their directions of motion or causing them to spiral. Static magnetic fields do not affect stationary charged particles.
Magnetic force does not do any work because it acts perpendicular to the direction of motion of the charged particle. Work is defined as force acting in the direction of motion, and since magnetic force acts perpendicular to the motion, it does not transfer energy to the particle in the form of work.
Magnets work in space because they create a magnetic field that can attract or repel other magnetic objects. This is possible because the magnetic field is not affected by the lack of air or gravity in space.
In outer space, magnets work the same way as they do on Earth. They create a magnetic field that can attract or repel other magnetic objects. This is because the movement of charged particles in space generates magnetic fields, which can interact with magnetic materials.
Yes, magnetic attraction can work underwater. However, the strength of the magnetic field may weaken depending on the material of the objects and the distance between them. Materials like iron and steel are more likely to be attracted by a magnetic field underwater compared to non-magnetic materials.
Why not? the desert is just the same as any other place on planet earth. Magnetic compasses work fine in the desert. See the "Where does the magnetic compass not work?" question for some places where they don't work.
They work by using a magnet.
There are still magnetic fields in space - especially if you remain close to Earth. But magnetic compasses are usually designed to use gravity, which you won't have if you are in free fall. A specially-designed magnetic compass would work, though.
No, the sun does not have an iron core to generate magnetic poles
No, a static magnetic field cannot do positive work on charged particles. Magnetic fields can only do work on moving charged particles by changing their directions of motion or causing them to spiral. Static magnetic fields do not affect stationary charged particles.
The age of rocks in ocean basins was determined through radiometric dating of volcanic rocks, which provides the absolute age of the rocks. Analyzing the magnetic properties of the rocks and the orientation of magnetic minerals helped in dating the rocks based on changes in Earth's magnetic field over time. Additionally, studying the distribution of fossils in the rocks provided relative dating information based on the known ages of the fossils.
How do magnitized car crushers work?
Magnetic force does not do any work because it acts perpendicular to the direction of motion of the charged particle. Work is defined as force acting in the direction of motion, and since magnetic force acts perpendicular to the motion, it does not transfer energy to the particle in the form of work.
No, they are silly.
