A current i ampere flows along an infinitely long straight thin walled tube, then the magnetic induction at any point inside the tube is:
tesla
tesla
Text Solution
Verified by ExpertsB
Let R be radius of a long thin cylindrical shell.
To calculate the magnetic induction at a distance r (r < R) from the axis of cylinder, a circular loop of radius r is shown:
Since, no current is enclosed in the circle so, from Ampere’s circuital law, magnetic induction is zero at every point of circle. Hence, the magnetic induction at any point inside the infinitely long straight thin walled tube (cylindrical) is zero.
