Can Magnetic field lines pass through the current carrying conductor?if yes then how?
Answers
Answer:
hi.
A current carrying conductor creates a magnetic field around it, which can be comprehended by using magnetic lines of force or magnetic field lines. The nature of the magnetic field lines around a straight current carrying conductor is concentric circles with centre at the axis of the conductor.
The electric field inside a current carrying conductor is zero be because the charges are distributed on the surface of the conductor. But, magnetic field is created around the current carrying conductor. The moving charges create a magnetic field around the conductor.
Explanation:
If current is flowing then yes. There is an electric field which causes the electrons to drift (flow in a particular direction). Moving electrons (and any other moving charged particle) creates a magnetic field.
The electric field gradient will be small if the conductor has good conductivity but there will still be some gradient to induce electron drift. For example, the voltage drop across a copper wire may be so small it is difficult to measure while the voltage drop across the same length of a lower conductivity wire e.g. niachrome wire will be easily measurable.
