What else can I help you with?
Are the magnetic field lines open or closed curves?
Magnetic field lines are closed curves, meaning they form continuous loops that originate from the north pole and loop back to the south pole of a magnet. This represents the continuous flow of the magnetic field in a closed loop.
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 happens to the magnetic field when opposite charges are brought together?
When opposite charges are brought together, the magnetic field is not affected. Magnetic fields are produced by moving charges, not static charges. So, bringing opposite charges together will not change the magnetic field in the vicinity.
At what rate is the magnetic field changing?
The rate at which the magnetic field is changing is known as the magnetic field's rate of change.
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.
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.
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.
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
Are the magnetic field lines open or closed curves?
Magnetic field lines are closed curves, meaning they form continuous loops that originate from the north pole and loop back to the south pole of a magnet. This represents the continuous flow of the magnetic field in a closed loop.
Is magnetic field a conservative field?
Yes, the magnetic field is a non-conservative field. This means that the work done by a magnetic field on a charged particle moving in a closed path is generally not zero, unlike a conservative field where work done in a closed path is zero.
Is earth's magnetic field in an closed iron box more than the magnetic field outside the box?
No, the Earth's magnetic field cannot be contained within a closed iron box. Iron is a ferromagnetic material that can distort and redirect magnetic field lines, but it cannot increase the total magnetic field strength. The magnetic field inside the box would be the same as that outside the box.
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 happens to the magnetic field when opposite charges are brought together?
When opposite charges are brought together, the magnetic field is not affected. Magnetic fields are produced by moving charges, not static charges. So, bringing opposite charges together will not change the magnetic field in the vicinity.
What happens when white light passes through a strong magnetic field?
I have the impression that light is not affected by magnetic fields - at least in a vacuum. If traveling through other substances, the magnetic field can change the light's polarization.
At what rate is the magnetic field changing?
The rate at which the magnetic field is changing is known as the magnetic field's rate of change.
Which direction does magnetic fields flow?
I think it is a mistake to refer to magnetic field 'flowing. Magnetic fields just are, they can change, and these disturbances might move in space, but the field itself does not flow. That being said, and assuming you meant to ask in which direction a magnetic field points the answer is that a magnetic field points towards the south pole of a magnet and away from the north pole. A magnetic field cannot be divergent (i.e. there are no sources) and any field line must be closed.
What happens when the magnetic field or or more magnets overlap?
they combine and become one magnetic field
