A solenoid 50cm long has 4 layers winding of 350 turns each if the current carried is 6 A .extimate the magnitude of magnetic field Near the Center of the solenoid of its axis
Answers
Therefore the Magnetic field near the centre of solenoid is 2.11 × 10¯² T .
Given : A solenoid 50cm long has 4 layers winding of 350 turns each if the current carried is 6 A.
To find : The magnitude of magnetic field near the centre of the solenoid of its axis.
solution : number of turns per unit length, n = (4 × 350)/(50/100 m)
= 2800 turns per metre.
current passing through the solenoid, I = 6 A
we know, Magnetic field near the centre of the solenoid of its axis is given by, B = μni
= 4π × 10^-7 × 2800 × 6
= (4π × 28 × 6) × 10^-5 T
= 2,110.08 × 10^-5 T
= 2.11 × 10¯² T
Therefore the Magnetic field near the centre of solenoid is 2.11 × 10¯² T
