Magnetic Effect of Current:
An electric current (i.e. flow of electric charge) produces magnetic effect in  
the space around the conductor called strength of Magnetic field or simply  
Magnetic field.
Oersted’s Experiment:
(Hans Christian Oersted (1777-1851)
When current was allowed to flow through a  
wire placed parallel to the axis of a magnetic  
needle kept directly below the wire, the needle  
was found to deflect from its normal position.

When current was reversed through the wire,  
the needle was found to deflect in the  
opposite direction to the earlier case.

Rules to determine the direction of magnetic field:
Imagining a man who swims in the direction of current from  
south to north facing a magnetic needle kept under him such that  
current enters his feet then the North pole of the needle will  
deflect towards his left hand, i.e. towards West.

Ampere’s Swimming Rule or SNOW Rule:
If the forward motion of an imaginary right handed screw is in the  
direction of the current through a linear conductor, then the direction  
of rotation of the screw gives the direction of the magnetic lines of  
force around the conductor.
