What is the magnetic field in the empty space enclosed by the toroidal solenoid of radius R?
The magnetic field inside a current carrying toroidal solenoid is B, if its radius is doubled and the current through it is also doubled keeping the total number of turns same, the magnetic field inside the solenoid will be:
A solenoid coil of 300 turns /m is carrying a current of 5 A. Calculate the magnitude of magnetic intensity inside the solenoid.
