A magnet is a material that produces a magnetic field. It is a substance which strongly attracts to special metals such as iron, cobalt, nickel and other iron-containing metals.
The magnetic field is defined as an area around a magnet where a magnetic force is experienced. A magnetic field is represented by field lines and are also called Magnetic lines of force.
What are Magnetic Effects of Electric Current?
The magnetic effect of electric current is mainly defined as the flow of an electric current in a conductor produces a magnetic field around it. This theory of the magnetic effect of electric current was discovered by H.C Oersted in the year 1820 and is also known as an electromagnetic effect.
This theory can be clearly observed by performing a simple experiment with the help of a compass. In this experiment, the needle of the compass moves as the compass is brought closer to the current carrying conductor. This law proves that electric current produces a magnetic effect.
Properties of a Magnet
The three main properties of a magnet are:
- Magnets have two poles: North and the south.
- The force of attraction of a magnet is greater at its poles.
- Like poles repel each other and unlike poles attract each other.
