Moving coil galvanometer operates on a Permanent Magnet Moving Coil(PMMC) mechanism and was designed by the scientist D'arsnoval. It is of two types: (i) Suspended coil (ii) pivoted coil type / tangent galvanometer. Its working is based on the fact that when a current carrying coil is placed in a magnetic field, it experiences a torque that rotates the coil about its axis of suspension in such a way that the magnetic flux passing through the coil is maximum. |
Which of the following is done to make the field radial in a moving coil galvanometer? |
number of turns of the coil is kept small magnet used is a horse shoe magnet poles are of very strong magnets poles are cut cylindrically |
poles are cut cylindrically |
In order to obtain the radial magnetic field in a moving coil galvanometer, the poles of the magnet are cut cylindrical. |
