    Fig. shows a car sticking to an electromagnet. Name the forces acting on the car. Which one of them is larger?   

    Answer:

    The forces working on the object (car) are
    (i) Force of gravity (downwards),
    (ii) Magnetic force (upwards).                                                                                                      
    Since the car is moving upwards, so magnetic force due to electromagnet is greater.
