When electrons are loosely held by the nucleus, they are able to travel freely within the limits of the body. (iv) Momentum Silver is the best conductor of electricity. The split ring reverses the direction of current in the armature coil after every half rotation, i.e., it acts as a commutator. But in this figure, we have shown only a galvanometer G connected between the two carbon brushes. Answer: What is the function of an earth wire? Solution: (d) vary continuously. The deflection can be observed in the opposite direction as compared with the previous case. The flux linked with the coil due to the magnetic field is at a constant. (d) The closer to the wire, the stronger is the magnetic field strength. So the current produced in the rotating coil can be tapped out through the commutator half rings into the carbon brushes. If the current in the coil A is changed, will some current be induced in the coil B? Field lines are close together near the poles. Answer: Certainly, there are some limitations but they serve as a very basic illustration of current and current flow. If a large amount of electric current passes through the wire, the wire may become so hot that it may melt and break. Question 3 Why do Mind Mapping Inputs and Outputs Matter? However, if the current is larger then it is possible that a noticeable amount of heat is generated. Working : When the armature coil ABCD rotates in a magnetic field produced by the permanent magnets, it cuts through the magnetic lines of force. Question 3 The two forces in the opposite sides are equal and opposite. When the coil rotates, it cuts the magnetic field lines due to which a current is produced in the coil. william.a.steigerwald@nasa.gov / nancy.n.jones@nasa.gov, Managed by the Mars Exploration Program and the Jet Propulsion Laboratory for NASAs Science Mission Directorate, CacheCam Image of Perseverance's 14th Sample of Martian Rock, Mars Report: How to Bring Mars Sample Tubes Safely to Earth.
