1.	Draw the pattern of magnetic field lines around a current-carrying straight conductor. How does the strength of the magnetic field produced change : (i) with the distance from the conductor ? (ii) with an increase in current in a conductor ?
Answer» Solution :The PATTERN of magnetic field lines has been shown here. The field pattern CONSISTS of closed circular paths around the CURRENT-carrying conductor. (i) The strength of the magnetic field PRODUCED decreases with increase in distance from the current-carrying conductor. (ii) The strength of magnetic field INCREASES on increasing the current flowing in a conductor.
