Magnet field lines curve out from one pole and return to the same pole True or false?
False.
Magnetic field lines curve out from one pole and return to the same pole?
No. Magnetic lines curve out from one pole and end up at the opposite pole. Please see the related links for illustrations.
Is it true or false that an electric charge creates a magnetic field?
Opposites attract, like charges repel each other.
What is meaning of horizontal component of earth's magnetic field?
If you think of the planet Earth as a very large round magnet, you can imagine the magnetic lines of force that come vertically out of the magnetic poles, then curve around to reach the opposite pole where they vertically return to the planet from the opposite direction. While the lines of force are parallel to the surface of the Earth, they are horizontal.
What is the significance of B-H curve?
H is the symbol for magnetic field strength, which is defined as the magnetomotive force per unit length of a magnetic circuit, where the magnetomotive force is provided by a current-carrying coil, wound around that magnetic circuit. Magnetomotive force is the product of the current flowing through the coil and the number of turns, expressed in amperes (although often spoken as "ampere turns").The magnetomotive force gives rise to the magnetic flux within the magnetic circuit, the intensity of which is termed flux density (symbol B), expressed in teslas.A B-H curve plots changes in a magnetic circuit's flux density as the magnetic field strength is gradually increased. The resulting shape indicates how the flux density increases due to the gradual alignment of the magnetic domains (atoms, that behave like tiny magnets) within the magnetic circuit material. When all the domains have aligned, the B-H curve reaches a plateau and the magnetic circuit is said to be saturated. At this point, any further increase in magnetic field strength has no further effect on the flux density. Different magnetic materials, such as iron, steel, etc., have B-H curves with different slopes and points at which saturation occurs.After reaching saturation, a reduction in the magnetic field strength results in a reduction in the flux density. However, the resulting curve does not quite match the original curve, but 'lags behind' it. This effect is called hysteresis, which is from the Greek, meaning to 'lag behind'.When the magnetic field strength reaches zero, the resulting curve indicates that the flux density has not, itself, reached zero. The value of flux density remaining is termed the remanence (or residual magnetism) of the magnetic material. 'Soft' magnetic materials, used in the manufacture of transformer cores, etc., will have a very small remanence; whereas 'hard' magnetic materials, used in the manufacture of permanent magnets, will have a very high remanence.In order to remove any remanence, the magnetic field strength requires to be reversed (by reversing the direction of the current in the coil) and increased in the opposite direction. The amount of 'negative' magnetic field strength necessary to completely remove the remanence is called coercivity.If we continue to increase the negative magnetic field strength, the magnetic material will again reach saturation in the opposite direction, and the new curve will be a mirror image of the original curve. The complete B-H curve is then usually described as a hysteresis loop. The area contained within a hysteresis loop indicates the energy required to perform the 'magnetise - demagnetise' process.'Soft' magnetic materials require relatively little energy to become magnetised and demagnetised and, so, have 'narrow' hysteresis loops, whereas 'hard' magnetic materials require a great deal of energy and have 'wide' hysteresis loops.So, B-H Curves and Hysteresis Loops are a valuable tools for comparing the characteristics and behaviour of different magnetic materials, in order to select them for an appropriate application.

Is an isochron a change in earth's magnetic field?
no false
What do field lines show that curve toward each other show?
It has No magnetic interaction
How is magnitude of a magnetic field calculated?
To get the magnitude of a magnetic field calculation you will have to do a few steps. First you will have to integrate around the curve starting at 0 and get the radians then you can get the total sum of P.
Since magnetic field lines are just constructs,the field cannot contain energy?
false
What is the purpose of B-H curve?
The purpose of the B-H curve is to quantify the relationship between the magnetic flux density (B) and the magnetic field strength (H) in a material. It helps in understanding the magnetic properties of materials, such as their magnetization behavior and saturation levels, which is essential for designing magnetic devices and systems.
Compass magnets can only be deflected by electromagnets such as Earth's magnetic field?
This is FALSE. TWICE!The Earths magnetic Field is not Electromagnetic.A compass can be deflected by any Magnet.
How are magnetic field lines arranged?
Magnetic field lines spread out from one pole, curve around the magnet, and return to the other pole.. . ah, they don't actually spread out from the poles, inside the magnet they are bunched together but they still form closed loops with the lines outside.
Is it true or false that an electric charge creates a magnetic field?
Opposites attract, like charges repel each other.
