This happens because he direction of coil in current is reversed, so there are continuous forces acting on coil to keep it turning. The steps of commutator working are: a)   Current flowing through the commutator causes side A to move upward and side B to move downwards. b)   ...

UNIT 6: Magnetism and Electromagnetism When a bar of magnet is hung from a thin thread and allowed to swing, it stops swinging and the pole of magnet facing the north side is known as the north pole and south-seeking pole is known as south pole. Metals such as iron, cobalt and nickel are magnetic which means a magnet will attract this metal. For example, if there are iron pins fallen then can be quickly collected with the help of a magnet. Two like pole (N and N pole, S and S Pole) will repel each other. But unlike poles will attract each other. Practical 1: Magnetic Fields  Method 1: a) Place a compass on a piece of paper, with pencil plot a dot on the north side of compass needle. b) Shift the compass to next position in contact with the dot and mark the position of second needle. c) Repeating the process so that a field line is traced from the north to the south pole in magnet with a...
