Re: What is the difference between electrical field and magnetic field?
The area which surrounds an electrically charged particle will have the electrical field around it.
The magnetic materials will posses the magnetic field around it. When a charge is moving, it does not only have an electric field, but a magnetic field as well. This is why electric and magnetic fields are always associated with each other. They are two different fields, but not a totally separate phenomena |

Re: What is the difference between electrical field and magnetic field?
Read the whole concept below and you will automatically understand the differences and the concept: Electric Fields vs Magnetic Fields The area that surrounds an electrically charged particle has a property,called electric field.This exerts a force on other charges or electrically charged objects. An electric field is expressed in Newtons per Coulomb in SI units.It is also equivalent to volts per meter. Field strength, at a given point, is described as the force that is exerted, with a positive test charge of +1 coulomb place, at that certain point.An electric field is considered as a vector quantity.The strength of such field is related to electrical pressure called voltage, and the force is carried through space from one charge to another charge. When a charge is moving, it does not only have an electric field, but a magnetic field as well. This is why electric and magnetic fields are always associated with each other. They are two different fields, but not a totally separate phenomena. Another term of reference has resulted from these two fields ‘electromagnetic’. The charges that move in the same direction produce an electric current.As was earlier mentioned, moving charges create a magnetic force. Thus, when there is an electric current, there is a magnetic field present.The magnetic fields strength is expressed in Gauss (G) or Tesla (T). Magnetic materials have magnetic fields around them, which are considered inherent. Magnetic fields are detected due to the force they exert on magnetic materials and other moving electric charges. The magnetic field is also considered as a vector field, as it has a specific direction and magnitude. An electric field has a force proportional to the amount of electric charge within the field, and the force is in the direction of the electric field. On the other hand, force of the magnetic field is proportional to the electric charge as well, but also takes into account the speed of the moving charge. The magnetic force is perpendicular to the magnetic field, and the direction of the moving charge. In electromagnetism, electric and magnetic fields oscillate at right angles to one another. It should be noted that each can exist without each other. The interaction between magnetic fields and electric fields are laid out in Maxwell’s equation. Important Points: 1. An electric field is a field of force, surrounding a charged particle, while a magnetic field is a field of force surrounding a permanent magnet, or a moving charged particle. 2. The strength of an electric field is expressed in Newtons per Coulomb, or Volts per meter, while a magnetic field strength is expressed in Gauss or Tesla. 3. The force of an electric field is proportional to the electric charge, while the magnetic field is proportional to the electric charge as well as the speed of the moving charge. 4. Electric and magnetic fields oscillate at right angles to one another. Good Luck!!! |

Re: What is the difference between electrical field and magnetic field?
hi dear,
Diff. between electric field and magnetic field. 1)The area that surrounds an electrically charged particle has a property, that is referred to as an electric field. This exerts a force on other charge,s or electrically charged objects. It was Faraday who introduced this concept. 2)An electric field is expressed in Newtons per Coulomb when in SI units. It is also equivalent to volts per meter. Field strength, at a given point, is described as the force that is exerted, with a positive test charge of +1 coulomb place, at that certain point. There is no way to measure field strength without the test charge, because ‘it takes one to know one’ when it comes to electric fields. An electric field is considered as a vector quantity. The strength of such field is related to electrical pressure called voltage, and the force is carried through space from one charge to another charge. 3)When a charge is moving, it does not only have an electric field, but a magnetic field as well. This is why electric and magnetic fields are always associated with each other. They are two different fields, but not a totally separate phenomena. Another term of reference has resulted from these two fields ‘“ ‘electromagnetic’. 4)The charges that move in the same direction produce an electric current. As was earlier mentioned, moving charges create a magnetic force. Thus, when there is an electric current, there is a magnetic field present. The magnetic field’s strength is expressed in Gauss (G) or Tesla (T). 5)Magnetic materials have magnetic fields around them, which are considered inherent. Magnetic fields are detected due to the force they exert on magnetic materials and other moving electric charges. The magnetic field is also considered as a vector field, as it has a specific direction and magnitude. 6)An electric field has a force proportional to the amount of electric charge within the field, and the force is in the direction of the electric field. On the other hand, force of the magnetic field is proportional to the electric charge as well, but also takes into account the speed of the moving charge. The magnetic force is perpendicular to the magnetic field, and the direction of the moving charge. 7)In electromagnetism, electric and magnetic fields oscillate at right angles to one another. It should be noted that each can exist without the other. For instance, Magnetic fields without an electric field can exist in permanent magnets (objects with inherent magnetism). Conversely, static electricity has an electric field without the presence of a magnetic field. 8)The interaction between magnetic fields and electric fields are laid out in Maxwell’s equation. 9)An electric field is a field of force, surrounding a charged particle, while a magnetic field is a field of force surrounding a permanent magnet, or a moving charged particle. 10)The strength of an electric field is expressed in Newtons per Coulomb, or Volts per meter, while a magnetic field strength is expressed in Gauss or Tesla. 11)The force of an electric field is proportional to the electric charge, while the magnetic field is proportional to the electric charge as well as the speed of the moving charge. 12)Electric and magnetic fields oscillate at right angles to one another. And also i am attaching the file of which that shows the complete detailed about difference between electric and magnetic field ALL THE BEST |
