Why does a compass needle get deflected when brought near a bar magnet? 

Once upon a time, a curious fox named Finnigan loved exploring the forest. He dreamt of finding hidden treasures, and his trusty compass, Bartholomew, was his guide. Bartholomew had a needle that always pointed faithfully north, thanks to a special secret. "Bartholomew's core was a tiny magnet, forever drawn to the Earth's magnetic north."

One crisp morning, Finnigan stumbled upon a clearing bathed in sunlight. In the center lay a smooth, black stone unlike anything he'd seen before. As he approached, Bartholomew went haywire! His needle, usually a steady north pointer, started twitching wildly.

Confused, Finnigan nudged the stone with his paw. Suddenly, a small, silver bar clattered to the ground. It looked just like a miniature version of the black rock! Finnigan, ever the investigator, picked it up and brought it closer to Bartholomew.

The closer the bar came, the more Bartholomew's needle "deflected from pointing north." Finnigan gasped! He realized the bar must be special too.

The truth dawned on him. "Both the bar and Bartholomew were magnets!" They each had an invisible field, like a gentle breeze pushing and pulling on anything magnetic nearby. When Finnigan brought the bar close, "its strong magnetic field overpowered the Earth's magnetism" that usually guided Bartholomew. This magnetic tug-of-war made Bartholomew's needle point in a completely different direction!

So, there you have it! A compass needle gets deflected by a bar magnet because the magnet's powerful field disrupts the compass's usual connection with Earth's magnetism. In short, it's a battle of magnetic forces!
