Describe with a diagram how magnetic field is generated inside a solenoid due to current passing through it.

How is the direction of a magnetic field vecB at a point related to the magnetic line of force passing throught that point?

Two long straight parallel conducts carrying steady currents I_(1) and I_(2) are separated by a distance d. Explain briefly with the help of suitable diagram, how the magnetic field due to one conductor acts on the other. Hence deduce the expression for the force acting between the two conductors. Mention the nature of this force.

How would you draw diagram of the magnetic lines of force produced due to flow of electric current through a straight conductor and indicate the directions of current and magnetic lines of force in that diagram.

How is the direction of a magnective field barB at a point related to the magnetic line of force passing through that point?

The magnetic field B within a solenoid of length L with N turns and carrying a current I is given by

Which ray deflects more when passing through magnetic field
