Compare the direction of the magnetic field inside a solenoid with that of the field there if the solenoid is replaced by its equivalent combination of north pole and south pole.

The magnetic field inside a solenoid is-

The location of the north magnetic pole is a latitude of

The strength of magnetic field inside a long current-carrying straight solenoid is:

Can we have a single north pole, or a single south pole?

(a)Using Ampere's circuital law, obtain the expression for the magnetic field due to a long solenoid at a point inside the solenoid on its axis. (b )How is the magnetic field inside a given solenoid made strong?

Distinguish between North pole and south pole of a magnet

The magnetic field along the axis of an air cored solenoid is B. The magnetic field energy density is

Draw magnetic field lines in and around a current carrying straight solenoid.

How do you find the north pole and south pole of a magnet?

Why can't two magnetic field lines cross each other? Draw the magnetic field lines (including field directions) of the magnetic field due to a long straight solenoid. What important property of this field is indicated by this field line pattern? Name any two factors on which the magnitude of the magnetic field due to this solenoid depends.
