PhysicsEasysingle choice
A current I ampere flows along an infinitely long straight thin-walled tube, then the magnetic induction at any point inside the tube is
Options:
Answer:
B
Solution:
Considering Ampere's loop (shown by dotted line), no current is enclosed by this loop. Therefore, the magnetic field will be zero inside the tube.
