Earth's magnetic field changes direction due to the movement of molten iron in the outer core. This movement generates electric currents, which in turn create the magnetic field. Over time, the flow patterns of the molten iron can change, causing the magnetic field to shift in direction.
What else can I help you with?
What is the direction of the induced current in a loop when there is a change in magnetic field direction?
When there is a change in the direction of the magnetic field in a loop, an induced current is generated in the loop in a direction that opposes the change in the magnetic field.
How do you change the direction of a magnetic field?
You can change the direction of a magnetic field by reversing the flow of electric current in a wire or by changing the orientation of a permanent magnet. Alternating the direction of current in a coil can also reverse the direction of the magnetic field it produces.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The magnetic field direction around the wire reverses when the direction of the current in the wire is changed. This is due to the right-hand rule that states the direction of the magnetic field is perpendicular to the direction of current flow.
What is the direction of the induced electric field?
The direction of the induced electric field is perpendicular to the change in magnetic field.
How do you reverse the magnetic field of an electromagnet?
To reverse the magnetic field of an electromagnet, you can either reverse the direction of the current flowing through the coil or change the polarity of the power supply connected to the coil. This will change the direction of the magnetic field produced by the electromagnet.

The direction of the induced electric field is perpendicular to the change in magnetic field.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire The magnetic field?
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
Can earths magnetic field change directions?
sorry I forgot the answer. dummy!
Why do scientists think that earths' magnetic field has not always pointed north?
Every 100,000 years or so, the Earths magnetic field shifts direction. North becomes south, south becomes north.
How do you reverse the magnetic field of an electromagnet?
To reverse the magnetic field of an electromagnet, you can either reverse the direction of the current flowing through the coil or change the polarity of the power supply connected to the coil. This will change the direction of the magnetic field produced by the electromagnet.
What happens to the magnetic field of wire when you change the direction of a current of the wire?
In that case, the magnetic field will also be reverted.
Why does the earths magnetic field change over time?
The Earth's magnetic field changes over time because that is the way that God makes it.
What happens to magnetic field of a wire when you change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
What happen to the magnetic field of a wire when change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
