Overview
Magnetism and electricity are closely linked. A current-carrying conductor produces a magnetic field around it, and a changing magnetic field can produce electric current. This connection explains magnets, electromagnets, electric bells, generators, and the safe use of electricity in homes and indus
Key Concepts
A magnet attracts iron particles
A magnet attracts iron particles and produces a magnetic field. The attraction of small particles of iron towards lodestone is called magnetism. A fre
Lodestone is a naturally occurring stone
Lodestone is a naturally occurring stone discovered by ancient Greeks. It is an oxide of iron, Fe3O4, and acts as a weak natural magnet. It is differe
The region around a magnet where
The region around a magnet where magnetic force acts is called the magnetic field. Magnetic lines of force start from the north pole and end at the so
When electric current flows through
When electric current flows through a conductor, a magnetic field is produced around it. If current increases, the magnetic effect becomes stronger. R
A solenoid is a long thin
A solenoid is a long thin coil of copper wire wound on a cylindrical form. When current flows through it, it behaves like a bar magnet. When soft iron
