sir i want to ask that why when we move a magnet around a wire or vice ,the current is being induced in wire and , is this  due to change in magnetic field as answered by google but i want to ask why does manetic field change  let us assume that it is changed then,  one expert answered that magnetic field is created around a wire which induces current and why does magnetic field is induced in wire and why magnetic field induces current.
 
 
pls answer the coloured rest is just explanation . I hope that you will understand my doubt and answer me with good explanation .
