When we ignite a candle it produces light. But light is EM wave. Then how electric & magnetic fields are produced on the ignition of candle.

Light is a form of energy. This energy has been shown to be both electric and magnetic. Atoms are electric and magnetic in nature. The combustion of a candle is an exothermic reaction which breaks down these electric and magnetic bonds and produces carbon dioxide and both infrared energy in the form of heat and visible light energy in the form of electromagnetic radiation. Light is radiated when the electrons in an elements involved in the reaction are excited because some external source of energy, in this case heat. Every element produces an different light signature when combusted.

I don't think there are any electric or magnetic fields when a candle is lit. We feel the heat and we see the light from the candle, and these are Electromagnetic waves, but there are no fields. The candle light is produced because the atoms in the candle wax are going through a chemical reaction called combustion, which usually produces an exremely bright light.

By incandescent heating of carbon particles. Electromagnetic waves are method of transmission, not the method of generation, all light is electromagnetic whether created by fusion, electric resistance, electric arc, or fire.
