Overview
The magnetic effect of electric current reveals the fascinating relationship between electricity and magnetism. This chapter explores how electric current creates magnetic fields, leading to practical applications like electromagnets, electric motors, and loudspeakers. Understanding this phenomenon
Key Concepts
When electric current flows through
When electric current flows through a conductor, it creates a magnetic field around it. This magnetic field can deflect a nearby magnetic compass need
To find the direction of magnetic
To find the direction of magnetic field around a current-carrying conductor: Hold the conductor with your right hand such that your thumb points in th
A solenoid is a coil
A solenoid is a coil of insulated wire wound in a spiral shape. When current flows through it, it behaves like a bar magnet with distinct north and so
For a current
For a current-carrying conductor placed in a magnetic field: First finger points in the direction of magnetic field (north to south), seCond finger po
A current
A current-carrying conductor placed in a magnetic field experiences a force. In motors, this force causes rotation of the armature. Split rings (commu
