Magnetic fields exist because physics views the Universe as three space dimensions and one time dimension. Actually, the Universe is quaternionic and contains four space dimensions, one real dimension r and three vector dimensions ix+jy + kz. Magnetic fields are just the electric field divided by the speed of light c= E/B = r/t. This means B=E/c. Time is t=r/c.
Maxwell's Equations without magnetic fields are:
0=XE=(dEr/dr - Del.Ev) + (dEv/dr + Del Er)
where E=Er + Ev and Er is the real field and Ev is the vector field.
The magnetic field is dE/dr= dE/cdt=dB/dt. This shows that the "magnetic field" is important when there is a real variation of the electric field, dE/dr.
The electromagnetic fields are related by c and z:
E = cB = zH = zcD
What else can I help you with?
Does a magnetic field exist around every object?
Yes, a magnetic field exists around every object that has a magnetic property.
What evidence shows that earth's magnetic field changes?
One piece of evidence is the study of ancient rocks that show reversals in magnetic orientation. Another evidence comes from observations of the movement of the magnetic poles over time. Additionally, observations of magnetic anomalies in the Earth's crust provide further evidence of changes in the magnetic field.
What evidence is there for the reversal of the magnetic field of the earth?
Evidence for the reversal of Earth's magnetic field is found in magnetic minerals in rocks that preserve the direction of the field when they were formed. These minerals show alternating patterns of magnetization that suggest the field has reversed multiple times throughout Earth's history. Additionally, studies of sediment cores and oceanic crust have also provided evidence of past magnetic field reversals.
What kind of evidence supports that magnetic fields exist?
One type of evidence is the observation of magnetic forces acting on magnetic materials such as iron filings aligning along the field lines. Additionally, experiments with compass needles demonstrate their orientation towards the Earth's magnetic field. Magnetic field lines can also be visualized using techniques like iron filings or magnetic field sensors.
A magnetic field exists around a wire whenever?
a current flows through it. The magnetic field is created due to the movement of charged particles (electrons) in the wire. The direction of the magnetic field is determined by the right-hand rule.
What evidence is there on earth having a magnetic field?
To start if we didnt have a magnetic field we would be fried by the suns radiation. The northern lights are evidence that we have a magnetic field surrounding earth.
What is evidence that an electrical current produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
Does a magnetic field exist around every object?
Yes, a magnetic field exists around every object that has a magnetic property.
What is pushing or pulling force that exists when a magnetic material is near?
Magnetic field
Is there any evidence that Titan have a magnetic field?
no it does not
What exists between the two poles of a magnet?
A magnetic field exists between the two poles of a magnet. This field is the region where magnetic forces are active and can influence other magnetic materials or objects within its proximity.
What evidence shows that earth's magnetic field changes?
One piece of evidence is the study of ancient rocks that show reversals in magnetic orientation. Another evidence comes from observations of the movement of the magnetic poles over time. Additionally, observations of magnetic anomalies in the Earth's crust provide further evidence of changes in the magnetic field.
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.

Additionally, studies of sediment cores and oceanic crust have also provided evidence of past magnetic field reversals.
Has the magnetic field of the ever flipped?
Yes, the magnetic field of the earth has flipped. The evidence is in fired pottery in historical times.
How can iron filings provide evidence that a bar magnet has a magnetic field?
They tend to align along the magnetic field lines.
How much has earth magnetic field decreased?
There is no evidence that it has decreased.
