Which magnetic field?
If you're talking about the earth, the magnetic poles have switched polarity in the past. The earth is not a solid magnet, it is a liquid, specifically molten nickel. When the molten nickel shifts the magnetic field of the earth can change.

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 an electric motors magnetic field to collapse?
the answer is rotational force
What causes Jupiter's magnetic field?
What causes it's magnetic field is 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.
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 property of an object that causes it to be affected by a magnetic field?
Charge

the answer is rotational force
What causes sunspots and solar flares?
Fluctuations in the sun's magnetic field.
How is earth a magnetic field?
The earth's magnetic field is caused by the fact that the earth has a moltern iron core. When moltern iron spins it causes an electric field. This causes an electromagnetic field. Some planets are too large or too small for the iron in their core to be molten.
