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.
What is magnetic field lines and its properties Class 12?
The magnetic field line is the imaginary path along which an isolated north pole will tend to move if it is free to do so . The magnetic lines of force are closed curves. They appear to converge or diverge at poles. outside the magnet, they run from north to south pole and inside from south to north.
What is magnetic field lines and its properties Class 10?
Magnetic field lines are imaginary lines around the magnet . The magnitude of a field is indicated by its line’s density. Near to South and North Pole of a magnet, the magnetic field is stronger and will get weaker when it moves away from the poles.
What are magnetic field lines?
Magnetic field lines are a visual tool used to represent magnetic fields . They describe the direction of the magnetic force on a north monopole at any given position. ... One useful analogy is the close connection between magnetic monopoles and electric charges.
What are magnetic field lines list the properties of magnetic field lines?
- They are closed continuous curve.
- They start from North Pole and ends on South Pole outside the magnet.
- Inside the magnet they move from South to North.
- No two magnetic field lines can interest each other at any point.
What are the properties of magnetic field Brainly?
The properties of magnetic lines of force are:
Thus, the magnetic field lines are closed curves . The relative strength of the magnetic field is shown by the degree of closeness of the field lines. That is, the field is stronger when the field lines are crowded. No two field lines intersect each other.
What are the properties of magnet?
They are: Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel. Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other. Directive Property – A freely suspended magnet always points in a north-south direction.
What are the properties of magnetic lines of force?
- Each line is a closed and continuous curve.
- They originate from the north pole and terminate at the south pole.
- They will never intersect each other.
- They are crowded near the poles where the magnetic field is strong.
What are the properties of electric field lines?
- Field lines never intersect each other.
- They are perpendicular to the surface charge.
- The field is strong when the lines are close together, and it is weak when the field lines move apart from each other.
- The number of field lines is directly proportional to the magnitude of the charge.
What is magnetic field lines Brainly?
Answer: A magnetic field is represented by a series of line around a magnet . The path along with north pole moves in a magnetic field is called magnetic lines of force or magnetic field line. The direction of magnetic field is taken to be the direction in which a north pole of compass needle move inside it.
Why are there no two magnetic lines?
The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point . This is not possible for a magnetic field to point in more than one direction at the same point.
What is the property of magnetic material?
Explanation: Magnetic materials have the property of retentivity in which the magnetic flux produced acts according to the external magnetic field. When the external field is removed, the magnetization in the materials doesn’t deform immediately.
What are the three main properties of magnets write two to three paragraphs explaining all three properties?
3 properties of a magnet: The three properties that all magnets have are that they all attract certain metals, they have north and south poles, and two of the same poles will repel each other , while opposite poles will be attracted to each other.
What are the properties of electric field lines Class 12?
- These field lines never intersect each other.
- These field lines are perpendicular to the surface of the charge.
- The magnitude of charge and number of field lines both are proportional to each other.
What are three properties of electric lines of force?
- The electric lines of force start from a positive charge and ends on a negative charge.
- The electric lines of force always enter or leave the charged surface normally.
- Electric lines of force can never intersect each other. Was this answer helpful?
What are the properties of magnets for Class 6?
- A magnet attracts magnetic materials towards itself.
- A freely suspended bar magnet always aligns in the north-south direction.
- Unlike poles attract each other and like poles repel each other.
- A magnet with a single pole does not exist.
What are the properties of magnets and ferromagnetic materials?
- The atoms of ferromagnetic substances have permanent dipole moment present in domains.
- Atomic dipoles in ferromagnetic substances are oriented in the same direction as the external magnetic field.
- The magnetic dipole moment is large and is in the direction of the magnetizing field.
Why do field lines never intersect?
Electric lines of force never intersect because, at the point of intersection, two tangents can be drawn to the two lines of force . This means two directions of the electric field at the point of intersection, which is not possible.
What is the nature of magnetic field lines around a current carrying wire?
Magnetic lines of force around any current carrying conductor are circular in nature .
What are magnetic field lines justify the following statement a two magnetic field lines never intersect each other B magnetic field lines are closed curves?
(b) Magnetic field lines are closed curves or forms a closed loop . This is because two magnetic field lines can never intersect. And forming closed curves enable the lines to run different from each lines and not intersect to each other.
How magnetic properties are measured?
By measuring the apparent weight of the sample with the field gradient on , and off, we can measure the force on the sample resulting from its net magnetisation, and thus the susceptibility. This technique is known as the Faraday method, and works for small samples.
What is the origin of magnetic property of the material?
The magnetic properties of the material arises from electrons present in the atoms . Electrons are the charged particles and they are in motion which produces the magnetic field.
