The magnetic flux density B( in tesla ) inside the solenoid and parallel to its axis is given by the expression
B= permeability of free space x n x I, where n is the number of turns per metre length of the solenoid
my question is so for example, if n = 100turns in 1m and I = 2Ampere
in 1m length of solenoid B= permeability of free space x 100 x 2A
how about the B-field in like 10cm of the same solenoid?
i still use the same formula B= permeability of free space x 100 x 2A? or use 10 instead of 100?
2. does the length of solenoid affect the magnitude of B-field in the coil??
thanks for the help
