# magnetic field definition

• ### Magnetic FieldDefinition Formula Measurement Units

Magnetic field is an invisible space around a magnetic object. A magnetic field is basically used to describe the distribution of magnetic force around a magnetic object. Magnetic fields are created or produced when the electric charge/current moves within the vicinity of the magnet.
