Question

Part A - Imagine moving along the axis of the current-carrying loop in the figure, starting at a point well to the left of the loop and ending at a point well to the right of the loop.   How would the magnetic field strength vary as you moved along this path?

Part B - Would the magnetic field direction vary as you moved along the path?

Yes or No?

Explanation please

C) Magnetic fields of a current-carrying loop and a current-carrying coil (solenoid) Notice that the field of the loop and, especially, that of the coil look like the field of a bar magnet (see Fig. 27.11) 2016 Pearson Education, Inc.

Explanation / Answer

Part (A) IN LOOP

as we move from left to right first strenght increses till the centre of coil and then decreses because the field lines are close and dense at the centre.

IN SOLENOID

strength first increses till the left end of solenoid then remain same along the lenght of solenoid and then decreses from left end of solenoid because the field lines are coser and dence along the lenght inside the solenoid.

Part B)

No,
magnetic field direction remain same because the direction of current in the coil and solenoid remain same so direction of fkield lines is same.
