Q4 Physics Summative

While switching electrical current from a battery on and off, Hans Christian Orsted made an interesting observation. He noticed that every time the electrical current was flowing from the battery, the needle on his compass would be deflected. Which fundamental force was responsible for this observation?

• Electromagnetic force

• Weak force

• Strong force

• Gravitational force
