Draw a diagram of the magnetic lines of force to show that a current carrying solenoid is equivalent to a bar magnet.

Define magnetic lines of force.

In case of a current carrying solenoid

Show with the help of a diagram the nature of the magnetic lines of force normal to the plane of current carrying circular coil.

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.

Write down the properties of the magnetic lines of force.

Define magnetic moment of a bar magnet .

Sketch a graph to show the variation of the magnetic field due to a circular current carrying coil with distance along its axis on both sides of its centre.

What will happen if a current carrying solenoid is suspended horizontally with a thread?

A current carrying loop behaves as a magnetic dipole-explain .

State Ampere's circuital law. Use this law to find the magnetic field due to a straight infinite current carrying wire. How are the magnetic fields lines different from the electrostatic field lines ?
