in the previous lesson, you have learned about the interrelationship between electricity and magnetism. You were also able to discover how an electric field could create a magnetic field and vice versa. As a review, a magnetic field is created around a wire that conducts electric current. A coiled wire, known as a solenoid, acts as a magnet when current flows through it. A solenoid with a core of iron acts as a strong magnet which is called as electromagnet Based on what you have learned previously, how can you describe electromagnetism?​
