Magnetic field due to solenoid is given by
A solenoid of length and diameter possesses 10 turns per . A current of is flowing through it, the magnetic induction at axis inside the solenoid is weber amp
gauss
tesla
.
A long solenoid is formed by winding 20 turns . The current necessary to produce a magnetic field of 20 millitesla inside the solenoid will be approximately
tesla - metre/ampere
A solenoid of length has a radius of and is made up of 600 turns If it carries a current of , then the magnitude of the magnetic field inside the solenoid is
Here, turns i.e.
Hence, we can use long solenoid formula, them
A long solenoid carrying a current produces a magnetic field along its axis. If the current is double and the number of turns per is halved, the new value of the magnetic field is
