Magnetic field lines indicate presence of a magnetic field
When current flows a magnetic field is generated around the flowing electrons.
Note:(a) This magnetic field is also called an electromagnetic field. (b) However, this magnetic field is the same magnetic field as the field made by two bar or a single horse shoe magnet

However, since the coil is energized, the CR 1 contacts are forced out of their normal position. They immediately open and cause an open circuit that de-energizes the coil.
