WebOnce it gets going, Lenz' law says it will create a back EMF that will oppose the original. The sum of that back EMF and the original lead to a lower total voltage to the motor once it reaches speed, and less current flowing through the motor, and then the lights get bright again. 3 comments. WebThe magnetic field from the solenoid aligns the magnetic domains inside the iron along the same direction. This domain alignment then creates a permanent net magnetic field inside the iron which supplements the external mag field from the solenoid since they are both aligned in the same direction. ( 7 votes) Nemo 10 years ago WebAccording to his theory it is intrinsic property of nature that an electric field exists in the space around an electric charge. This electric field is considered to be a force field that exerts a force on an other charges placed in that field. For example, a charge ‘q’ produces an electric field in space surrounding it. how new york voted 2020
