Introduction of Magnetic field

The magnetic field was discovered by Oersted in 1820. There are three rules in a direction of current and field they are; Right-hand thumb rule, Maxwell's corkscrew rule and Right hand first rule. Hall effect is a voltage is developed across the specimen in the direction perpendicular to the both the current and the magnetic field due to the applied magnetic field to a current carrying conductor and if a uniform magnetic field Bzis applied along the z-axis, it is found that an e.m.f. develops along the y-axis i.e. in a direction perpendicular to Ix and Bz. This voltage is called hall voltage. The magnetic field was discovered by Oersted in 1820.
