Long Questions
1. What challenges did Michael Faraday face in his early life?
Answer: Michael Faraday was born into a poor family and had a speech defect, which made other children laugh at him and teachers ignore him. He also had to leave school at 12 due to poverty and started working at 13, but he never let these difficulties stop him from learning.
2. How did Faraday become Humphry Davy’s assistant?

3. Why was the induction motor an important invention?
Answer: The induction motor, invented by Faraday, turned electricity into continuous motion, which was a big breakthrough. It led to the creation of many useful things like fans, cars, and trains, changing the way people lived and worked.
4. What did Faraday do with the Bavarian glass Davy gave him?
Answer: Davy gave Faraday an impossible task to figure out how Bavarian glass was made, and though he failed after four years, he kept a piece as a reminder. Years later, he used that same glass to prove light, electricity, and magnetism are connected, turning his failure into a success.
5. How did James Maxwell help Faraday’s work become famous?
Answer: Faraday couldn’t explain his discoveries with math because he lacked formal education, so his ideas weren’t fully accepted. James Maxwell, a skilled mathematician, turned Faraday’s drawings and ideas into equations (Maxwell’s Equations), making them useful for modern technology like electronics.
