Explain - ''Changing electric field produces magnetic field''. Explain importance of this statement.

Explanation

Maxwell logically showed that by changing electric field magnetic field can be obtained. This phenomena is very important.
This phenomena first time was shown by Oersted who was physics teacher.
This phenomena explain radiowaves, gamma waves, electromagnetic waves and other forms of electromagnetic waves.
Production of magnetic field by changing electric field can be explained charging of capacitor by using Ampere circuital law.
