What is the basic difference between electric and magnetic field lines?

What is the basic difference between electric and magnetic field lines?

The electric field is defined by straight field lines. They do not form closed loops. Magnetic field lines form a closed loop starting from the north pole and terminating at the south pole outside the magnet.

What is the difference between magnetic field and magnetic field intensity?

magnetic field strength, also called magnetic intensity or magnetic field intensity, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre.

What are magnetic field lines?

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

What is the difference between the magnetic field strength B and magnetic induction H?

The B field is also known by the names magnetic flux density and magnetic induction. Magnetic induction is simply a process by which a magnetic field generates a magnetic field in another object by just being within the vicinity of the object.

What shape are the magnetic field lines?

concentric circles
Magnetic field lines form in concentric circles around a cylindrical current-carrying conductor, such as a length of wire. The direction of such a magnetic field can be determined by using the “right-hand grip rule” (see figure at right).

What are electric field lines?

An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point. The relative closeness of the lines at some place gives an idea about the intensity of electric field at that point.

What is magnetic field of electric current?

Magnetic Effect of Electric Current – A magnetic field is a force field that is created by magnetic dipoles and moving electric charges, and it exerts a force on other nearby moving charges and magnetic dipoles. Magnetic Field is a vector quantity because it has both magnitude and direction.

What is the difference between magnetizing field and magnetic field?

Question: What is the difference between Magnetic Intensity and Intensity of Magnetisation? Answer: The magnetic intensity defines the forces that the poles of a magnet experiences in a magnetic field whereas the intensity of magnetization explains the change in the magnetic moment of a magnet per unit volume.

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 electric field lines and properties?

    An electric field line is an imaginary line or curve drawn from a point of an electric field such that tangent to it (at any point) gives the direction of the electric field at that point. Properties : 1. Electric field lines starting from positive charge and terminating at a negative charge.

    What is the relationship between electric and magnetic fields?

    The magnetic field is related to the electric field in such a way that magnetic fields moves perpendicular the electric field. This relationship exists between a magnetic field and an electric field is a consequence of associating elementary particles.

    What are electric magnetic fields?

    Electric and magnetic fields (EMFs) are invisible areas of energy, often referred to as radiation , that are associated with the use of electrical power and various forms of natural and man-made lighting. EMFs are typically characterized by wavelength or frequency into one of two radioactive categories:

    What really is a magnetic field?

    A magnetic field is a vector field that describes the magnetic influence of electrical currents and magnetized materials. In everyday life, the effects of magnetic fields are most readily encountered with nearby permanent magnets, which pull on magnetic materials (such as iron) and attract or repel other magnets.

    What are the units of magnetic field strength?

    In general, a device that measures the strength of a magnetic field is called a magnetometer. The official SI unit for magnetic field strength is the tesla (T). Magnetic field strength is also measured in units of gauss (G) (1 G = 10-4 T).
