What are magnetic flux lines?
What are magnetic flux lines?
The magnetic flux is the net number of field lines passing through that surface; that is, the number passing through in one direction minus the number passing through in the other direction (see below for deciding in which direction the field lines carry a positive sign and in which they carry a negative sign).
What is Earth’s magnetic line?
The Geographic North Pole is defined by the latitude 90° N and is the axis of the Earth’s rotation. The Magnetic North Pole is where the Earth’s magnetic field points vertically downward. The Earth creates its own magnetic field from the electric currents created in the liquid iron-nickel core.
Which best describes Earth’s magnetic field lines?
The field lines bend away from the second south pole. Which best describes Earth’s magnetic field lines? The field lines go out of Earth near Antarctica, enter Earth in northern Canada, and are not aligned with the geographic poles. The magnetic pole near Antarctica is a north pole.
What is the magnetic flux density of Earth?
The Earth’s magnetic flux density is about 4 lines per sq inch, or 0.5 Gauss, or 5*10-5 Tesla.
Can we see magnetic flux lines?
At each end of a magnet is a pole. These lines of flux (called a vector field) can not be seen by the naked eye, but they can be seen visually by using iron fillings sprinkled onto a sheet of paper or by using a small compass to trace them out.
What are the 3 properties of magnetic field lines?
Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows:
- The field is tangent to the magnetic field line.
- Field strength is proportional to the line density.
- Field lines cannot cross.
- Field lines are continuous loops.
Which electromagnet is the strongest?
Bitter electromagnets have been used to achieve the strongest continuous manmade magnetic fields on earth―up to 45 teslas, as of 2011.
How do you describe Earth’s magnetic field?
Earth’s magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the Earth’s interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.
Is Earth a magnet?
In a sense, yes. The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface. So we could say that the Earth is, therefore, a “magnet.”
What is the symbol of magnetic field?
Index to magnetic terms & units in the SI
| Quantity name | Quantity symbol | Quantity symbol |
|---|---|---|
| magnetic field strength | H | Φ |
| magnetic flux density | B | χρ |
| magnetic moment | m | J |
| magnetic susceptibility | χ | M |
Which is the best definition of magnetic flux?
Magnetic flux is defined as the number of magnetic field lines passing through a given closed surface. It provides the measurement of the total magnetic field that passes through a given surface area.
Which is the best definition of magnetic field lines?
This idea brings us to a different definition for the field lines: Magnetic field lines: The magnetic field lines are the trajectories a north magnetic monopole would follow when placed in the magnetic field. □. _square □. . Whether magnetic monopoles are real or not, the elegance of this idea is evident.
What is the equation for magnetic flux density?
where B is the magnitude of the magnetic field (the magnetic flux density) having the unit of Wb/m 2 ( tesla ), S is the area of the surface, and θ is the angle between the magnetic field lines and the normal (perpendicular) to S.
How are magnetic poles related to earth’s magnetic field?
Magnetic field lines (thin black lines) – describe the direction of the magnetic field outside of the Earth. C1, C2 = The Magnetic Poles – the points at which the magnetic field lines are exactly perpendicular to the Earth’s surface. The magnetic poles do not line up with the geomagnetic poles.
