Electric Field And Magnetic Field. A field that exerts a force on magnets or on certain metals like iron nickel and cobalt. In an electromagnetic field the electric field is perpendicular to the magnetic field whereas the magnetic field is perpendicular to an electric field. Relation between electrical and magnetic field class 12th and pollytecnic other competitive exam. A magnetic field is a field of force surrounding a permanent magnet or a moving charged particle.
Electrical wiring electrical equipment and power lines all produce electric and magnetic fields. Electrical fields and magnetic fields can be characterized. The electric field produces by a unit pole charge ie either by a positive or through a negative charge whereas the magnetic field caused by a dipole of the magnet ie the north and south pole. You thus have to choose one of them. In an electromagnetic field the electric field is perpendicular to the magnetic field whereas the magnetic field is perpendicular to an electric field. It is obtained by moving electric charges.
Energy of Electric and Magnetic Fields In electricity studies the position-dependent vectors E D H and B are used to describe the fields.
Units Of Measurement Expression The strength of an electric field is expressed in Newtons per Coulombs NC or Volts per meter Vm. Chapter 8 Electric and Magnetic Fields This chapter defines electric and magnetic fields and discusses typical field levels what factors affect field strength safety standards if any and expected average and maximum fields along the action alternatives. Difference Between Electric Field And Magnetic Field. Electric field lines are generated on positive charges and terminate on negative ones. In an electromagnetic wave the electric field and magnetic field are perpendicular to one another. The field lines of an isolated charge are directly radially outward.
