Basic principle for voltage generation in A. The answer is that you can think of every charge as being surrounded in space by an electric field.

## Difference between Electric & Magnetic Field

An example of magnetic flux density is a measurement taken in teslas. Home Dictionary Meanings Magnetic-flux-density. Magnetic-flux-density meaning. Magnetic flux density is defined as the amount of magnetic flux in an area taken perpendicular to the magnetic flux's direction. The amount of magnetic flux through a unit area taken perpendicular to the direction of the magnetic flux.

The magnetic flux per unit area perpendicular to the direction of the magnetic force: it is measured in teslas or gausses. A vector quantity measuring the strength and direction of the magnetic field around a magnet or an electric current.

Magnetic flux density is equal to magnetic field strength times the magnetic permeability in the region in which the field exists. Magnetic flux density also can be understood as the density of magnetic lines of force, or magnetic flux lines, passing through a specific area. It is measured in units of tesla. Related articles.

## Magnetic flux

The one of the major difference between the magnetic and electric field is that the electric field induces around the static charge particle which is either negative or positive, whereas the magnetic field produces around the poles i. Some other differences between them are explained below in the form of comparison chart. The region around the magnetic where poles exhibits a force of attraction or repulsion. It is perpendicular to the electric field. Field Vector Vector Field Line Induces on a positive charge and terminate on a negative charge Generate at north pole and terminate at the south pole. Loop Electric field lines do not form a closed loop. Magnetic line forms a closed loop.

In electromagnetism theory, it is absolutely clear that these are different quantities and you need to be precise about which you are measuring. For non-magnetic materials - for air, most building materials, the human body, etc - it has a value of very nearly 1. So, most of the time, it really doesn't matter whether too much whether we're measuring B, the magnetic flux density, in microteslas, or H, the magnetic field strength, in amps per metre. You can simply convert from one to the other, as we do in our table of units. Sometimes, people will be very precise and talk about either the magnetic flux density or the magnetic field strength. But actually "magnetic field" is perfectly valid as a description of either - both the magnetic flux density and the magnetic field strength are examples of a magnetic field. And just using "magnetic field" is a lot simpler

The most significant difference between the magnetic field and the magnetic flux is that the magnetic field is the region around the magnet where the moving charge experiences a force , whereas the magnetic flux shows the quantity or strength of magnetic lines produced by the magnet. The other differences between the magnetic field and magnetic flux are explained below in the comparison chart. The magnetic field and flux both are the properties of the magnet.

### Magnetic flux

Magnetic flux density is defined as the amount of magnetic flux in an area taken perpendicular to the magnetic flux's direction. The amount of magnetic flux through a unit area taken perpendicular to the direction of the magnetic flux. The magnetic flux per unit area perpendicular to the direction of the magnetic force: it is measured in teslas or gausses.

Magnetic flux is what generates the field around a magnetic material. It consists of photons, however, unlike the light we receive from the Sun, it is at a much lower frequency. The number of magnetic field lines passing through a surface such as a loop of wire. The magnetic flux through a closed surface such as a ball is always zero. The SI unit of magnetic flux is the Weber Wb in derived units: volt-seconds.

Electromagnetic Notes Pdf. The changes at a source will take a certain time to travel to a distant point. Static Electric Fields 3. Applications of electromagnetic fields and waves in industry and research. Faraday noticed that when he moved a permanent magnet in and out of a coil or a single loop of wire it induced an E lectro M otive F orce or emf , in other words a Voltage, and therefore a current was produced. And you know what? Light is those waves.

Magnetic flux is a measure of the number of magnetic field lines passing through an area. where is the angle between the magnetic field and the area vector.

In physics , specifically electromagnetism , the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. Magnetic flux is usually measured with a fluxmeter, which contains measuring coils and electronics , that evaluates the change of voltage in the measuring coils to calculate the measurement of magnetic flux. The magnetic interaction is described in terms of a vector field , where each point in space is associated with a vector that determines what force a moving charge would experience at that point see Lorentz force. The magnetic flux through some surface, in this simplified picture, is proportional to the number of field lines passing through that surface in some contexts, the flux may be defined to be precisely the number of field lines passing through that surface; although technically misleading, this distinction is not important. The magnetic flux is the net number of field lines passing through that surface; that is, the number passing through in one direction minus the number passing through in the other direction see below for deciding in which direction the field lines carry a positive sign and in which they carry a negative sign. If the magnetic field is constant, the magnetic flux passing through a surface of vector area S is. For a varying magnetic field, we first consider the magnetic flux through an infinitesimal area element d S , where we may consider the field to be constant:.

- If the flux in an stationary circuit changes, the induced current sets up a magnetic field opposite to the original field if original B increases, but in the same direction.
