Question

a solenoid has a radius 0.1 centimeters , length 3 centimeters if a 10 amp current in the solenoid produces a magnetic field 0.015 tesla calculate the number of turns. a solenoid has a radius 0.1 centimeters , length 3 centimeters if a 10 amp current in the solenoid produces a magnetic field 0.015 tesla calculate the number of turns. a solenoid has a radius 0.1 centimeters , length 3 centimeters if a 10 amp current in the solenoid produces a magnetic field 0.015 tesla calculate the number of turns.

Explanation / Answer

i = current = 10 A

B = magnetic field = 0.015 T

magnetic field inside a solenoid is given as

B = uo n i              n = number of turns per unit length

0.015 = (12.56 x 10-7) n (10)

n = 1194.27

N = Total number of turns

L = length = 3 cm = 0.03 m

so N/L = 1194.27

N = 1194.27 x 0.03

N = 35.83
