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.
A contour line that forms a closed loop and has small dashes pointing to the inside of the loop represents what?
Hysteresis loops tell about the magnetic properties of a material. E.g. wider loops indicate that the material is magnetically hard (i.e. it retains magnetisation even if the applied field is removed, permanent magnetics have much wider hysteresis loops)whereas thinner loops represent it to be soft (if the magnetic field is removed, the material doens't show any magentism). This is one advantage of hysteresis loops. further, such loops can identify the grain size of a material and much more. hope it answers your question.
What is a property of a magnetic field?
One property of a magnetic field is that its divergence is zero. That means that a magnetic field line is always a loop and that the net magnetic field coming out of or going in to an enclosed surface is always zero. The result of this is that there are no magnetic monopoles, at least none discovered. Theories, however, do abound.
When molten material hardens into the rock on the ocean floor the domains of the iron it contains?
align with Earth's magnetic field, freezing the magnetic orientation of those minerals. This creates a record of the Earth's magnetic field at the time of cooling, which scientists can study to understand past changes in the planet's magnetic field.
What happens if the electron enters the magnetic field parallel to B?
If an electron enters a magnetic field parallel to the field lines (i.e., parallel to B), it will not experience any deflection or force due to the magnetic field. This is because the force on a charged particle moving parallel to a magnetic field is zero.
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.
Best description of a magnetic field line?
A magnetic field line is an imaginary line that represents the direction a magnetic compass would point when placed at any point in space. The lines form closed loops around a magnet or current-carrying wire, flowing from the north pole to the south pole in a continuous path. The density of field lines indicates the strength of the magnetic field.

Choose the best description of a magnetic field line.?
A magnetic field line shows the direction a compass needle would point.
Do electric and magnetic fields always form closed loops?
Magnetic fields do, because there's no such thing as an isolated magnetic "pole", and a magnetic line always starts and ends at opposite poles of the same magnetized object. But electric fields don't. You can easily have a bundle of isolated positive charge over here and a bundle of isolated negative charge over there, whereupon the lines of the electric field start on one bundle and end on the other bundle. But electric field lines can also exist in closed loops, and they do that in radio waves, where the electromagnetic field propagates with an electric field component and a magnetic field component, and they both form closed loops.
Do magnetic fields line flow?
Magnetic field lines represent the direction and strength of the magnetic field at different points in space. They form closed loops and flow from the north pole to the south pole outside of a magnet, and from the south pole to the north pole inside the magnet.
What is the best description of a magnetic field line?
magnetic field line is an imaginary line showing magnetic energy between a north and south pole .
Choose the best description of a magnetic field line A Magnetic field lines for a bar magnet are parallel to the magnet B A magnetic field line shows the direction a compass needle would?
B. A magnetic field line shows the direction a compass needle would align in a magnetic field.
What is magnetic line of induction?
The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.AnswerThere is no such thing as a 'magnetic line of induction'. Induction is a process, by which a changing current induces (causes) a voltage into the same conductor or an adjacent conductor.A 'line' on the other hand, is imaginary and is simply a method of modelling a magnetic field in such a way that we can visualise its shape, rather in the same way that we use contour lines to show the shape of hills, etc.
How does a tangent at any point on the magnetic field line show the direction of magnetic field at that point?
The tangent to a magnetic field line at any point indicates the direction of the magnetic field at that specific location. This is because the tangent line represents the direction a compass needle would point if placed at that point on the field line. The magnetic field lines themselves flow from the north pole of a magnet to its south pole, with the tangent pointing in the direction the magnetic field would act on a north pole.
Which is true of magnetic field lines but not electric field lines?
they show wich way iron shavings would align themselves They always make closed loops. Electric field lines can either form closed loops or they can start and finish on isolated electric charges. Magnetic field lines always only form closed loops.
A contour line that forms a closed loop and has small dashes pointing to the inside of the loop represents what?
Hysteresis loops tell about the magnetic properties of a material. E.g. wider loops indicate that the material is magnetically hard (i.e. it retains magnetisation even if the applied field is removed, permanent magnetics have much wider hysteresis loops)whereas thinner loops represent it to be soft (if the magnetic field is removed, the material doens't show any magentism).
