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 called north pole or north seeking.
- The pole of a magnet which points toward south direction is called south pole or south seeking.
- Like poles of magnets repel each other while unlike poles of magnets attract each other.
Similar to other effects; electric current also produces magnetic effect. The magnetic effect of electric current is known as electromagnetic effect.
It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.
