A solenoid of 1200 turns is wound uniformly in a single layer on a glass tube 2 m long and 0.2 m in diameter. The magnetic intensity at the center of the solenoid when a current of 2 A flows through it is:
Text Solution
Verified by ExpertsThe correct answer is:
B
Magnetic field at center inside the solenoid is given by
So magnetic intensity at center
H=1.2 x 10 3 Am -1
