Q. What is Magnetic Flux?
Its the measurement of the total magnetic field passing through a given area.
Q. What is the magnetic flux through a closed surface?
Magnetic flux through a closed surface is always zero
Q. What is the unit of magnetic flux?
The unit of Magnetic Flux is tesla-meter2 or weber(Wb)
Q. What is Gauss's Law of Magnetism?
Gauss Law of Magnetism states that the surface intergral of the magnetic field over a closed surface is equal to zero.
Q. Can DC be generated By the principle of electromagnetic Induction?
no,by EMI,YOU CAN GENERATE AC
Q. why we don't consider no. of turns in writing flux in mutual inductance whereas we consder in self inductance?

Q. Is it true that when direction of any object is reversed from its previous direction then direction of induced current will also change?
direction of rotation of object change,direction of emf also changes.
