explain the magnetism produced by electric current. give an example
Answers
Answer:
An electromagnet consists of a long coil of insulated copper wire wound around an iron rod. When the two ends of the coil are connected to a cell, a current passes through the coil and produces a magnetic effect. This magnetic effect magnetises the iron rod. So, the iron rod becomes an electromagnet.
Explanation:
The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.
