• Electric current generates magnetic field. At the same time, a changing magnetic field produces electric current. This interplay of electricity and magnetism is widely used in a number of electrical devices and appliances in modem age technology.

• Magnetic field due to current in a long straight wire: Take a straight, thick copper wire and pass it vertically through a hole in a horizontal piece of cardboard. Place small compass needles on the cardboard along a circle with the centre at the wire. All the compass needles will point in the direction of N - S.
• Important 2nd year physics chapter 14 Important long questions for Intermediate part-II students.
• Now pass a heavy current through the wire. It will be seen that the needles will rotate and will set themselves tangential to the circle. On reversing the direction of current, the direction of needles is also reversed. As the current through the wire is stopped, all the needles again point along the N-S direction.

• Following conclusions can be drawn from the above mentioned experiment: (i) A magnetic field is set up in the region surrounding a current carrying wire.
• Important 2nd year physics chapter 14 conceptual questions for Intermediate part-II students.
• (ii) The lines of force are circular and their direction depends upon the direction of current. (iii) The magnetic field lasts only as long as the current is flowing through the wire.
• Important 2nd year physics chapter 14 long questions for Intermediate part-II students.
• The direction of the lines of force can be found by a rule concluded directly from the above experiment which is stated as follows:  "If the wire is grasped in fist of right hand with the thumb pointing in the direction of the current, the fingers of the hand will circle the wire in the direction of the magnetic field".

• Force on a current carrying conductor in a uniform magnetic field: We have seen that a current carrying conductor sets up its own magnetic field. If such a conductor is placed in an external magnetic field, the magnetic field of the conductor will interact with the external magnetic field, as a result of which the conductor may experience a force.
