Magnetism.

Q.1 (Pic.1)For induced current they told it not depends upon time but from the equation it is clearly, how??? Q.2 (Pic.2) the highlighted line is true for that particular case only right ???? because for the other cases motion is in the direction of force so not possible to be perpendicular correct or not ???

  • Ravi prakash yadav thankyou
    induced current depends on change in flux with respect to time where flux is given as B.dA. So if we change either magnetic field (B) or area (dA) with respect to time,the induced ...

    ques 2) highlighted line is talking about only magnetic force because m.f is q V cross B means cross product so M.F is always perpendicular to V and B, any force which is defined a...
