Draw the magnetic field lines due to a circular loop of area `vecA` carrying current I. Show that it acts as a bar magnet of magnetic moment.
`vecM=IvecA`

Illustrate the magnetic field produced due to circular loop carrying an electric current.

Draw magnetic field lines around a bar magnet.

Draw the magnetic field lines due to a straight wire carrying current.

An observer to the left of a solenoid of N turns each of cross section area ‘A’ observes that a steady current I in it flows in the clockwise direction Depict the magnetic field lines due to the solenoid specifying its polarity and show mat it acts as a bar magnet of magnetic moment m = NIA
