Question

What was Faraday's ground breaking discovery?

• A. Electricity can be used to produce magnetic effect
• B. Moving magnets can produce electricity
• C. Opposite magnetic poles attract just like opposite electric charges attract
• D. Magnets can bend light

Answer 1

The correct option is B Moving magnets can produce electricity

Faraday discovered that moving magnets or changing magnetic field near a coil results in an induced emf across the coil. This was a ground breaking discovery as it led to the invention of devices like generator, induction motors, induction cooking devices etc.
