  Magnetic effects of electric current Brief summary: Magnetic Effect of Electric Current Properties of magnet: A free suspended magnet always point towards north and south direction. The pole of a magnet which points toward north direction is named North Pole or north seeking. The pole of a magnet which points toward south direction is named South Pole or south seeking. Like poles of magnets repel each other while unlike poles of magnets attract each other. Similar to other effects; current also produces magnetic effect. The magnetic effect of electrical current is understood as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected due to flow of electricity. This shows that electric current produces a magnetic effect. The imaginary lines of magnetic flux around a magnet are called line of force or line of force of magnet. When iron fillings are allowed to settle around a magnet , they get a...
