If a magnet is dropped through a circular coil carrying current its acceleration as it passes through the coil would decrease increase remain same become zero. How would the thickness of a coil used in a generator affect the e.m.f induced? increase decrease no change become zero. State one use of eddy currents (though they are considered a loss). check level of oil in cars helps to control the stearing helps to maintain aerodynamics helps to find speed of car. A coil is passed thorugh U-shaped magnet (just between tw sides) and current is passed. This U-shaped magnet is placed on a weighing balance. If current is increase how would it affect the weight of magnet. decrease as current increases no change increase as current increases depends on polarity of current passed. Are electric motor and generator same thing or different? They are fully different as their construction and working both are different. They are different from the point of how they work but construction is same. Their construction is different but working is same. They are same in every way and aspect. Is it possible to interconnect a motor and a generator so as to get continous supply of energy. Motor can run the generator and vice versa. yes it is possible as one will transfer the energy to other yes this is partially possible but motor has to be smaller than generaotor no it is not at all possible as we need to do some work to keep running any one of them. none of the above answer is right. Could there exist a different force like electro-gravity (like we have electromagnetism). yes why not we could link both since electrons also experience the gravitational field. yes why not since gravitational field is quiet strong no since electrostatic field is quiet weak no since gravitational field is very weak compared to electric field.
