A current in a long straight wire produces a magnetic field. These magnetic field lines?
The magnetic field lines are arranged circularly around the wire.
Does a lodestone create a magnetic field?
A lodestone is magnetized and thus produces a magnetic field around it. This can be detected by the deflection of a compass needle.
Charge moving through a wire produces a magnetic field around the wire?
Yes, it does.
How electric current have magnetic effect?
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
Earth's magnetic field results from movements in the what?
The Earth's magnetic field results from electric currents in the mantle and outer core around the iron solid core; every electricmagnet is prduced as a result of electricity flowing around a iron core - the same principle works in our own magnetic field.
Which layer of the earth produces its magnetic field?
The earth's outer core produces the magnetic field.
What is the layer in which the magnetic field of the Earth is produced?
The outer liquid core produces the strong magnetic field of the Earth, through the dynamo effect.
A current in a long straight wire produces a magnetic field. These magnetic field lines?
The magnetic field lines are arranged circularly around the wire.
Is there a electromagnetic field around the earth?
No, there is a magnetic field round the Earth.
What does the rotation of the solid inner core produce?
It produces earth's magnetic field.
Does a lodestone create a magnetic field?
A lodestone is magnetized and thus produces a magnetic field around it. This can be detected by the deflection of a compass needle.
Does lightning produces magnetic field?
Yes, The movement of electrical charges produces a magnetic field
Does the magnetic field around the earth as you get ferther away from earth?
Yes and no.
How did the earth get the magnetic field?
Because there's a magnet in the centre of the earth which is known that it's the source of gravity. It's magnetic field is around the earth obviously.
Why does a magnetic field create around the earth when the earth spins on its axis?
The Earth spins on its axis purely because of the conservation of momentum. The material of which it was formed had a net spin and this is what we observe. The magnetic field is caused by the flow of liquid material not far beneath the crust. This flow generates an electrical current, and this in turn produces the magnetic field. This current flows approximately parallel to the Equator.
Charge moving through a wire produces a magnetic field around the wire?
Yes, it does.
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.
