✱Faraday law of Electrolysis:-
According to faraday if we change magnetic flux through the given loop then there must be change on indusedal EMF.
EMF-Electro Magnetic Force
The Magnitude of induced EMF is related with rate of change of flux.It does not depend on absolute value of flux
Eind=-dΦ/dt
✱Mathematical form of faraday law:-
- Method which can used to change the Magnetic Flux
- By changing magnitude of magnetic field
- by changing magnitude of Arial vector.
- By changing relative orientation of magnetic field and Area vector
The flux of magnetic field due to induced current opposes the change in flux that causes the indused current.
Explanation:-If the change in flux is "increase"then According to Lenz law indused current opposes this "increase" i.e flux from magnetic field of indused current will pass through the loop in the direction opposes to that of original flux so that of which increasing.
Basis of Lenz law is conservation of Energy because opposition of cause of Indused EMF will help the consevation of Energy in to one form to another form.
If we move a bar magnet towards the loop of wire than we observed that slightly deflection galvanometer.
Which indicates the presents of small current original of this current can be explain on the basis of faraday Law ,according to this the motion of bar Magnet towards the loop increasing the amount of flux and this change in flux will be responsible for Iind(Induced Current).Induction will be Exist till there will be relative motion between bar magnet and coil.
