On a day to day basis, there is no change in the Earth's magnetic field to any significant degree that you might be able to notice with a compass. However, with sensitive instruments one can detect that the Earth's magnetic field changes continually in both magnitude and direction.
It might be particular interest to know that the location of the poles are changing and the North magnetic pole is moving about 30 miles or 50 kilometers per year.

What is a following characterizes a reaction at equilibrium?
At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. The concentrations of reactants and products remain constant over time. The equilibrium constant, which is the ratio of product concentrations to reactant concentrations, is constant at a given temperature.
What is equal at equilibrium in a chemical reaction?
At equilibrium in a chemical reaction, the rates of the forward and reverse reactions are equal. This means that the concentrations of the reactants and products remain constant over time.
What of the following characterizes reaction at equilibrium?
At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction, resulting in a constant concentration of reactants and products. The system is in a state of balance, where the concentrations of reactants and products remain constant over time.
When a reversible reaction is occurring in both directions at the same rate?
The reaction is at dynamic equilibrium, where the rate of the forward reaction is equal to the rate of the reverse reaction. The concentrations of reactants and products remain constant over time.
What happens when a reaction is at equilibrium?
When a reaction is at equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time, creating a balanced state where no further changes occur.
Is it true that the earths magnetic field always stayed the same?
No, the Earth's magnetic field is not constant and has changed in strength and direction over geologic time. This phenomenon is known as geomagnetic reversal, where the magnetic north and south poles switch places. The Earth's magnetic field is influenced by processes in the planet's outer core, so changes are to be expected over time.
What is the geomagnetic reversal time scale?
The geomagnetic reversal time scale has patterns of polarity. It is the pattern of alternating and reserved polarity in rocks.
Does the gravitational constant change over time or is it a constant value?
The gravitational constant, denoted as G, is considered to be a constant value in physics. It is a fundamental constant that is believed to remain the same over time and across the universe.
What has the author Folke Eleman written?
Folke Eleman has written: 'On some real and apparent time variations in the geomagnetic field' -- subject(s): Geomagnetism, Magnetic storms
Is an electric field associated with an electromagnetic wave constant in time?
No, the electric field oscillates in magnitude and direction as it propagates in the electromagnetic wave.
What is an unsteady flow?
An unsteady flow refers to a fluid flow where the properties at a specific point in the flow field change with time. This could be due to variations in velocity, pressure, or density over time. It contrasts with steady flow, where these properties remain constant at any given point in the flow field over time.
What is genetic equilibrium and how does it describe a population in which the allele frequencies remain constant and do not change over time?
Genetic equilibrium is a state in which the allele frequencies in a population remain constant and do not change over time. This means that the population is not evolving and there is no change in the genetic makeup of the population.
How long ago did the earths magnetic field reverse itself?
The last time that Earth's magnetic field reversed itself was 780,000 years ago. See the related link for two timelines showing geomagnetic reversals in Earth's history.
Can the velocity of a body remain constant in circular motions?
No. Since the object's direction changes all the time, it follows that its velocity is not constant. Its speed, on the other hand, may or may not be constant.
When is the next geomagnetic storm?
The timing of geomagnetic storms is difficult to predict accurately in advance. Monitoring agencies such as NOAA Space Weather Prediction Center provide real-time updates on geomagnetic activity and storm forecasts. It is recommended to check their websites or space weather apps for the most recent information on geomagnetic storms.
What three traits appear at an early age and remain constant over time?
extraversion, neuroticism and psychoticism
How a scientist would know to draw isochrons to connect basalt florws on land?
the data gathered from continental basalt flows allowed scientists to construct the geomagnetic time scale. Continental basalt flows were used to construct the geomagnetic time scale. long term changes in earth's magnetic field are called epochs. short term changes are called events :D
