What are the properties of magnetic fields?

Answer 1

They always form a closed loop.

They always start from the north pole and ends in the south pole.

They never intersect each other.

Magnetic lines of forces that are parallel to each other and are in the same direction repel each other.

Answer 2

Magnetic fields are created by moving electric charges. They exert a force on other moving charges and are characterized by their direction and strength. They can be visualized using field lines that indicate the direction of the force at any given point.

Answer 3

Magnetic lines of force have the following important properties:

They all have the same strength.

The lines never cross one another.

They seek the path of least resistance between opposite magnetic poles. They attempt to form closed loops from pole to pole.

Their density decreases when they move from an area of higher permeability to an area of lower permeability.

Their density decreases with increasing distance from the poles.

They are considered to have direction as if flowing, though no movement occurs.

They flow from the south pole to the north pole within a material, and north pole to south pole in the air.

Answer 4

1)they never intersect each other.

2)they move from north to south outside the magnet and south to north inside the magnet.

3)they are invisible.

4) are each of equal strength.

5)they are closed continuing curves. 6) appear to be massless. 7) travel at C ("speed of light"). 8) carry photons from the stars (electromagnetism). 9) are constantly moving. 10) can be broken. 11) are produced by moving charge.12) are responsive to all magnetic fields. 13) they all connect to dipoles.

Answer 5

Properties of magnetic lines of force:

1. They form closed curve which outside the magnet is directed from north pole to south pole & inside the magnet from south pole to north pole

2. They can never intersect each other

3. They contact longitudinally and repel each other literally

4. Number of lines per unit area at a point is proportional to the magnetic field at that point

5. At neutral point there cannot be any lines of force

6. They can emanate or terminate on the surface of magnet at any angle

7. They exist inside every magnetic field

8. Total magnetic flux enclosed in a surface is zero

9. If a soft iron is placed in a magnetic field , all the lines will pass through ring and no line will pass through space inside the ring .

10. They do not exist inside a super conductor.

Answer 6

The three most basic and fundamental properties of magnetic fields on the ordinary macro scale are:

1. A magnetic field is created by a moving electric charge (i.e. an electric current) as described by the Biot-Savart law and Ampere's law.
2. A magnetic field is created by a changing electric potential, known as the Maxwell displacement current.
3. A changing magnetic field creates an electric potential, as described by Faraday's law and Lenz's law.

Magnetic field properties and electric field properties are inextricably intertwined. The combined properties of electric and magnetic fields are summarized by Maxwell's Equations, four equations which together comprise all the fundamental laws of macro scale electromagnetics; all the rest is applications of those four.

Electromagnetic field theory looks different on the microscopic scale, ruled by quantum mechanics, when things are moving very fast, ruled by relativity.

Answer 7

At a given location, you could measure the strength of the field in both the horizontal and vertical directions.

From this you may determine the azimuth of the field at your location, its polarity, and its dip angle.

In addition, the field will vary in strength throughout the day.

And if the Earth is subject to a 'solar storm' at that time, the variability may well be rapid.

Answer 9

magnetic lines of forces are always continuous in the form of lopes

strength of magnetic field is proportional to the number of lines per unit area.

Answer 10

Negative and positive.
