Technician B says two magnetic fields are required for motor action: one in the casing and the other in the rotating armature..
Consequently, what is Motor Action?
Answered Aug 13, 2017. Generator action is it converts mechanical energy into electrical energy . Where ever magnetic flux cuts the conductor it induced en EMF . Motor action is quite opposite to generator action . It concerts electrical energy into machanical energy .
how does the magnetic field work? Magnetic fields are areas where an object exhibits a magnetic influence. The fields affect neighboring objects along things called magnetic field lines. A magnetic object can attract or push away another magnetic object. You also need to remember that magnetic forces are NOT related to gravity.
Similarly, how do you measure the strength of a magnetic field?
The Magnetic Field Intensity or Magnetic Field Strength is a ratio of the MMF needed to create a certain Flux Density (B) within a particular material per unit length of that material. H = At/m, ampere-turns per meter. Often, N is used as the number of turns of wire around a core or magnetic material. So the H = N*I/m.
What is the difference between B and H?
B is magnetic flux density, whereas H is magnetic field intensity. H has units of amp-turn/meter, whereas B has units of weber/turn-meter^2.
