Magnetic Effects of Electric Current – Notes
Magnetic Effects of Electric Current
When an electric current passes through a conductor, a magnetic field is created around the conductor. This phenomenon is known as the magnetic effect of electricity.
A magnetic field is the extent of space surrounding a magnet where the magnet’s effect can be felt.
Magnetic field lines represent the lines of action of the force acting on a unit north pole placed in a magnetic field.
