Every material is influenced to some extent by a magnetic field. Magnetism: Magnetism is physical phenomenon that is mediated by magnetic fields. Learn about how consumption of electricity takes place in households. When an alternating emf is applied to the primary coil, a changing current flowing in it produces an alternating magnetic flux in it. Items that do not get attracted to magnets are called non-magnetic. Current electricity is the most common form of electricity that is used to power up devices and appliances. Magnetic force of lines are continuous curve because magnetic lines of force starts at north pole and ends at south pole externally whereas south pole to north pole internally.
