)A long solenoid is embedded in a conducting medium and is insulated from the medium. If the current through the solenoid is increased at a constant rate, the i

Great!! you have pointed out the right thing...In question they should mention the current through which portion of the conducting medium. Here we are actually getting a volume cu...

Why Electric field is proportional to emf? as integration( E. dl) =Emf. then E*2pi*r =Emf. and now this EMf is proportional to the current. means only right hand side should be pr...

You just imagine a circular disc of radius r, perpendicular to the axis of the cylinder and find the magnetic flux through this disc. For better understanding you can study Griffit...

1.The induced current is proportional to induced emf which is proportional to induced circumferential electric field here. 2. Since the value of B is nonzero inside the solenoid we...

first of all the 1)induced current is asked not the Electric fied 2)2ndly the value of B = (neu)o nI is valid inside the solenoid not outside it. then? how is this response is vali...
