Q3. How to Show that Electric Current Generates Magnetic Effect?
Ans: The electromagnetic effect can be developed by the magnetic effect of electric current. When we bring a compass closure to a current-carrying conductor, the compass’s needle gets deviated due to the flow of electricity. This method is meant to show that the electric current produces a magnetic effect.
