A raft of negligible mass and length 4 m floats at rest on water with zero viscosity (no friction if the raft should move). A 40 kg person stands at the left end of the raft and a 60 kg person stands at the right end. When the people switch positions (each walks to the opposite end), what distance does the raft move in the water

answera compound;

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
