Difference Between Magnetic Field & Magnetic Flux
The major difference between the magnetic field and the magnetic flux is that the magnetic field is the region in which moving charges and poles experience a force. In comparison, the magnetic … Read more
What is Magnetic Flux? Definition & Properties
The current flows in an electric circuit. In a same way, the flux flows in a magnetic circuit. Flux is thus analogous to electric current. The Greek letter Phi or Phi suffix B is its symbol. Its symbol is Ø and Øm.
