Earth's molten outer core rotates. That outer core is made up mostly of molten iron. The movement of the molten iron produces the magnetic field.
When currents in the outer core force the solid inner core to spin at a slightly faster rate than the rest of the planet causes the Earth to have a magnetic field.
What else can I help you with?
If a landlord filed an eviction then dropped it before the court date is it still on the renter's record?
No. But it may still be in the court records forever, filed under the names of the parties.
How often are public records updated?
All the time. As soon as a document is filed by an official agency (local, state, national, etc.) it is deemed a publicly available record.
In what ways do electrons act like particles?
A: If a nucleus is a point like a flag pole then the electrons are orbiting this nucleus at a very big distance like football filed distance and they have a charge too
What does 'consent to rate' mean on a workman's comp bill?
Consent to Rate means that the insurance company must have the consent of the insured (i.e. by a signed form) to charge higher than the filed (with the State, if applicable in your state) rate. **** More information** To elaborate on the above answer, Florida is a good example of a state that allows Consent to Rate - these forms must be signed prior to binding. the resons for consent to rate would be Unable to Obatin Coverage at the filed rate, Unfavorable loss experience, unusual hazards or claims activity and such.

If you filed chapter 13 six months ago and you have been offered a job in another state will you be able to rent an apartment?
Depends on the landlord and their credit requirements. Most likely, yes, but you may be required to put down additional money as a deposit.
Is Earth is an electromagnet?
Earths electromagnetic field is essiential to life on earth. Its deflects all the harmful radiation given off by the sun and in deep space. It is widely accepted that it is generated by our earths core. The core at the centre of the earth spins at a tremendous rate and the energy that it creates by doing this is thought to give of the electromagnetic energy.
What layer of the earth produces its magnetic filed?
The outer core of the Earth, which is composed of molten iron and nickel, creates the planet's magnetic field. As the Earth rotates, the movement of this liquid outer core generates electric currents, which in turn produce the magnetic field.
What is an example of a magnetic field?
The atmosphere of the earth is a magnetic filed
What is the direction of magnetic filed lines?
The direction of magnetic field lines are from north to south
Can insulated conductors carry eddy current due to magnetic filed?
i not give u
How do rocks record changes in earths magnetic field?
Rocks which are liquid (lava) have their magnetic particles aligned to the local magnetic field as they cool and solidify. The rocks can be dated by the radioactive decay processes. If there is a new layer of rock (lava) laid down over this same deposit and the magnetic filed has altered, the new rock will have a different imposted magnetic field and age than the older rock.
Has Nokia come filed a patent for a vibrating tattoo?
Yes they have. The patent is for a magnetic vibrating tattoo that can pick up signals from magnetic fields. The tattoo will vibrate when the person who has it receives alerts from their phone.
What is the region of space affected by Earths magnet filed is called?
The region of space affected by Earth's magnetic field is called the magnetosphere. It acts as a protective shield around the Earth, interacting with the solar wind and trapping charged particles. This region extends tens of thousands of kilometers into space on the side facing away from the Sun.
How eddy current changes the coil resistance and impedance?
When an AC generator provides an alternating current to the coil will induce the magnetic filed around it. This is called primary magnetic field. The impedance is nothing but the opposition to the current flow. The coil will have resistance as well as inductance. When this coil is brought to near any conducting material, due to the primary magnetic filed the eddy currents will develop in the material. The magnetic filed which will induce in the material is called secondary magnetic field due to the eddy current secondary magnetic field will try to oppose the primary magnetic field due to any change in the eddy current pattern. Once primary magnetic filed gets affected in the coil definitely there will be a change in impedance in terms of resistance and inductance.You can think of eddy currents as current flowing in the wrong direction (across laminations in transformers, for example). This energy is effectively lost, causing a higher loss, increasing the resistance. Eddy currents will have a minimal effect on impedance, since this is typically much larger than the resistance (note impedance is the resistance and reactance of the coil, reactance will typically dominate).
What role is played by molecular magnets to magnetize and demagnetize bodies?
The relative coercitivity of a material helps to magnetize and demagnetised a substance. If the coercitivity id low then the material can be easily demagnetized and vice versa. A substance can be magnetized by creating magnetic filed of opposite charges and demagnetized by creating same filed of charges.
What is true about magnetic field lines but not electric filed lines?
Magnetic field lines form closed loops, while electric field lines start and end on charges. Also, magnetic field lines do not begin or end; they always form continuous loops.
Does everything have a magnetic field?
No. Magnetic field arises due to a specific arrangement of electrons inside a substance. Hmm, I'd guess Yes. When there is electricity, there is a magnetic filed. Whenever an electron moves, not only does its electric field move, but also a magnetic field may be appreciated (if you are not moving with the electric field). OK, so gravity doesn't have a magnetic field.
