Does the moon have a stronger magnetic field than the earth?
Venus does not have a magnetic field.
Saturn Magnetic Field?
Yes, Saturn has a magnetic field that is produced by electric currents. I guess that also means it is going to be a real challenge for scientists to enter Saturn in the future.
Can other planets besides the earth have a magnetosphere?
The magnetosphere is the region around a planet where the solar wind is significantly altered due to the magnetic field of the planet. Planets with a magnetic field arising from internal processes are said to have a global magnetic field. A Global magnetic field will produce a magnetosphere. Six of the planets have global magnetic fields, and hence some magnetosphere; Mercury, Earth, Jupiter, Saturn, Uranus, Neptune. Mars did have one, but when the core froze, that ended the geodynamo. Venus, the near twin of Earth, does not have a geomagnetic field and that is quite perplexing. It too lacks a geodynamo and no one knows why. There are remnant magnetic fields for Mars and Venus, but they are too small to have any significant effect on the solar wind. Jupiter and Saturn have huge magnetic fields and there are only general theories as to what causes them. Uranus has a middling magnetic field, more in the range of Earth's field. The moon has no significant field. We have no idea whether Pluto does or not, but it would be unlikely.
What does a moving magnetic field generate?
This is field
Which planets have a magnetic field?
Planets with a magnetic field:-Mercury (weak field)EarthJupiterSaturnUranusNeptunePlanets with no magnetic field:-VenusMars (no field now, but it did have a field once. Some effect is still present in the oldest rocks)All Planets have cores are made up of heavy metals (Nickel and Iron). The spinning of molten cores cause friction. This constant friction causes the metals' electrons to spin in the same direction, producing the charged currents of opposite magnetic poles. When the core is very dense, the magnetic field is very strong.Typically, electrons return to spinning opposite each other, as happens when a planet's cooling core slowly solidifies. This cancels out the magnetic effects back to a neutral net charge.Dynamo theory suggests that convection in the outer core, combined with the Coriolis effect, creates the Earth's magnetic field. The solid inner core is too hot to hold a permanent magnetic field (see Curie temperature) but probably stabilizes those generated by the liquid outer core.Recent evidence has suggested that the inner core of Earth may rotate slightly faster than the rest of the planet. In August 2005 a team of geophysicists announced in the journal Sciencethat, according to their estimates, Earth's inner core rotates approximately 0.3 to 0.5 degrees per year relative to the rotation of the surface.
What is jupiters magnetic field caused by?
The dynamo effect
What is the leading theory for what causes earth's magnetic field?
The Dynamo Theory it what causes Earth's Magnetic Field
Do electric field causes magnetic field?
Yes.
Where does the convection that causes earths magnetic field?
The convection that causes Earth's magnetic field happens in Earth's molten outer core.
What is Jupiters gravitational field strength?
Jupiters gravitational field strength is 25 Nkg^-1
Can magnets attract objects without touching them?
A magnet has a magnetic field around it. The magnetic field causes a magnetic force that can attract objects to the magnet.
What is collected data about jupiters magnetic field and polar regions?
Data collected about Jupiter's magnetic field and polar regions provides valuable insights into the planet's composition and dynamics. It helps scientists understand the interaction between Jupiter's magnetic field and its atmosphere, as well as the formation and behavior of its auroras. Additionally, studying Jupiter's magnetic field and polar regions can provide information about the planet's internal structure and its magnetic interactions with its moons.
What property of an object that causes it to be affected by a magnetic field?
Charge
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
Are electromagnetic waves characterized by rarefactions and compressions?
No they are caused by changes in magnetic and electrical fields. When a magnetic field changes it causes an electric field that is perpendicular to it. And vice versa a changing electric field causes a perpendicular magnetic field. These changing fields propagate outwards at the speed of light and are what is meant by an electromagnetic wave.
What is the causes of electromagnetic induction?
Change in magnetic flux.iechange in magnetic field (B).change in the area vector/ area of magnetic field under the closed circuit (A).The angle between area vector and magnetic field .......xomagnetic flux = cosxo . A . B
What causes sunspots and solar flares?
Fluctuations in the sun's magnetic field.
