Is magnetic field conservative field?
it is not a conservative feild....it is a non conservative feild
Which of the following correctly describe magnetic field line?
APEX: Field lines that are close together indicate a stronger magnetic field. They don't affect the magnet that created them. They never cross. They begin on north poles and end on south poles.
What does gauss law of magnetism say?
Gauss's law of magnetism states that the magnetic flux through a closed surface is always zero, indicating that there are no magnetic monopoles (isolated magnetic charges) present. In simpler terms, magnetic field lines always form closed loops, with no beginning or end points.
Why emf is not zero when field current is zero?
Even when the field current is zero, there can still be a residual magnetic field present in the system, which can induce an electromotive force (emf) in a nearby conductor. This phenomenon is explained by Faraday's law of electromagnetic induction, where a changing magnetic field can induce a voltage in a closed loop.
What is used to represent magnetic field lines on a diagram?
Curved lines are used to represent magnetic field lines. The closer together they are, the stronger the magnetic field. Arrows are added to show the direction a north pole would move if placed at that point.
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.
Where is the edge of a magnetic field?
The edge of a magnetic field is typically considered to be where the field strength diminishes significantly. It can be defined as the point where the influence of the magnetic field becomes negligible or comparable to the background magnetic field in the area. The specific location of the edge of a magnetic field can vary depending on the strength and orientation of the magnetic source.
Are the lines that map out the magnetic field around a magnet?
The lines that map out the magnetic field around a magnet are called magnetic field lines. These lines indicate the direction of the magnetic field and its strength at different points around the magnet. Magnetic field lines are closest together where the magnetic field is strongest and they form closed loops that do not intersect.
Is magnetic field conservative field?
it is not a conservative feild....it is a non conservative feild
Can magnetic field be parabolic?
No, magnetic fields are typically represented by field lines that form closed loops or straight lines. They do not exhibit a parabolic shape.
What happens when there is a change in the magnetic field in a closed loop of wire?
When there is a change in the magnetic field in a closed loop of wire, an electromotive force (EMF) is induced in the wire, generating an electric current. This phenomenon is known as electromagnetic induction, described by Faraday's law of electromagnetic induction. The induced current creates a magnetic field that opposes the change in the original magnetic field.
How does Amperes law relate to the calculation of the magnetic field around a current-carrying wire?
Ampere's law states that the magnetic field around a closed loop is directly proportional to the current passing through the loop. This law is used to calculate the magnetic field strength around a current-carrying wire by integrating the magnetic field along a closed loop surrounding the wire.
Can there be any magnetic flux through closed surface?
No, according to Gauss's law for magnetism, the total magnetic flux through a closed surface is zero. This is because magnetic monopoles do not exist, so the magnetic field lines always form closed loops.
How is electricity and megnetisem related?
When a change occurs within a magnetic field there is an an electrical current present within a wire. As the electricity flows through the wire a magnetic field. The changing magnetic field creates a magnetic field. As this pattern continues these two fields induce each other through space.
Describe magnetic line of induction?
Magnetic lines of induction, also known as magnetic field lines, are imaginary lines used to represent the direction and strength of a magnetic field. They always form closed loops, flowing from the north pole of a magnet to the south pole. The density of magnetic field lines indicates the strength of the magnetic field in a particular region.
