Hans Oersted experiment

You all know that the needle of the compass always points in the #north_south direction
But when a #magnet comes near it, the needle of the
compass deflects. Thus the #magnetic_needle deflects whenever it interacts with another magnetic field.
On this note let's do an activity with an electric cell and a wire. Connect the two ends of the wire to the two terminals of the cell, so an electric current flows through the wire. See the needle of the compass under the wire deflects towards the west. The needle comes back to it's original position when we stop the current.
Now turn the cell to change its polarity. The direction of the current through the conductor changes
The needle now deflects in the opposite direction i.e. towards the east.
Wondering where is the other magnetic field that deflects the needle? Is it the current carry wire? Yes it is!
From this experiment, it was a Dutch scientist named Hans Christian Oersted (1820) who concluded that - A magnetic field is produced around a current carrying conductor. This is called the #magnetic_effect_of_electric_current.
This effect of electricity is used in many appliances like electric fans, mixers, etc.
