Magnetic Effects Of Electric Currents Trivia Quiz

Let’s start the quiz

We observe the magnetic effect of electric current, when a compass is brought near the conductor, the needle of the compass is deflected due to the flow of electricity. This shows that electric current creates a magnetic effect, this effect of electric current is called the magnetic effect of electric current, and the magnetic effect of electric current is known as the electromagnetic effect. The area around a magnet where its magnetic effect can be experienced is called the magnetic field, the direction and force of the magnetic field are represented by the magnetic lines of force. So let's start this quiz and Compare your knowledge about the Magnetic Effects Of Electric Currents.
