When is a magnetic field is the strongest on a magnet?
The magnetic field is strongest at the poles of a magnet where the magnetic field lines are most concentrated and closest together. This is where the magnetic forces are most intense.
Where is a magnets pull the strongest?
The north and south poles.
What is the name of the semicircles joining the poles?
tne name of the semicircle joining the poles to poles is called merdian
What is something that has two poles called?
A magnet has two poles, known as the North Pole and the South Pole.
Why does it tends to be cool at the earths pole?
The poles receive less direct sunlight due to the tilt of the Earth's axis, resulting in cooler temperatures. Additionally, cold air tends to sink towards the poles as warm air rises near the equator, contributing to the chilly conditions. The presence of ice and snow at the poles also reflects sunlight, further lowering temperatures.
Where are the Suns rays least direct on the earth?
At the poles
Where is the suns energy less entense on earth?
At the poles.
How are the suns rays different at the equator compared to the poles?
Only in the angle of incidence.
What is The Polar Flip Is it something to be concerned about?
Polar Flip is a occurrence when the positions of the Earth's magnetic poles are switched. Theories suggest this can lead to mass extinction and erosion of the atmosphere.
What is often hidden in the suns glare?
Mercury
What do strips of low-intensity magnetism represent on the ocean floor?
it represents the fact that the magnetic poles of the Earth must "flip" from time to time - the iron in the magma that cools to become the ocean floor aligns with the poles so stripping would show that the poles have changed direction over time. Some scientists suggest the times when the poles "flip" match up with cataclysmic events in the Earths geologic history.
How long is the suns rotation?
25 days for a rotation at the equator, 34 days for a rotation near the poles.
Why dont the magnetic crystals under the sea change direction when the poles flip?
because magnets cannot attract under water
Does Earth's magnetic field change?
Yes constantly, it is affected by the Solar wind and about every 100 thousand years the poles flip.
Does the flipping over of the earth's magnetic poles mean that thee whole planet physically flip over?
no. the polarity changes only
How will you magnetize two north poles?
Two north poles will repel each other due to their like magnetic charges. To "magnetize" them together, you would need to flip one of them around so that it becomes a south pole. This will create attraction between the two poles and they will come together due to the magnetic force.
Why does ice covers the poles?
Because - although the polar regions receive the same amount of sunlight as the rest of the planet, the angle of the suns rays to the earth means that less energy is absorbed - making the north & south poles much colder.
