Magnetic effect of current class 10 Eduscore Questions with solution

Image
Question :1     A proton enters in a straight line in a uniform magnetic field along the field direction. How will its path and velocity change? Answer:    As the proton is moving along the field direction, thus no force acts on it and the velocity and the path will not change. It will keep on moving with the same speed along the field direction. Question :2     A positive charge is moving vertically upwards in magnetic field towards south. In which direction will it be deflected? Answer:    If positive charge is moving upwards the corresponding current is also upwards, the magnetic field is towards south. Using Fleming’s left hand rule force is towards east and deflection towards east. Question :3     Free electrons always keep on moving in the conductor. Even then no magnetic force acts on them in a magnetic field. Why? Answer:    In the absence of external potential di...
