NEET Physics Question - Magnetic Effects of Current

Rankers Physics

Topic: Magnetic Effects of Current

Subtopic: Ampere's Circuital Law

If a long hollow copper pipe carries a direct current, the magnetic field associated with the current will be :

only inside the pipe

only outside the pipe

both inside and outside the pipe

neither inside nor outside the pipe

Inside the pipe current enclosed will be zero so magnetic field will also be zero. Outside the pipe there will be net Magnetic field
