Magnet Behavior and Experiments

The video tutorial demonstrates that a freely suspended magnet always aligns itself in the north-south direction. The experiment requires a bar magnet, a wooden block, and a plastic tub half-filled with water. Initially, the magnet is suspended freely, and it is observed to align north-south. Then, the magnet is tied to a wooden block and floated in water, where it again aligns north-south after being disturbed. This activity proves that both freely suspended and static magnets in water point towards the north-south direction.

What are the materials required for the experiment to show that a freely suspended magnet always points towards the north-south direction?

• A bar magnet, a plastic tub, and a wooden block

• A bar magnet, a metal tub, and a wooden block

• A bar magnet, a plastic tub, and a metal block

• A bar magnet, a glass tub, and a wooden block

What should you do after suspending the bar magnet freely?

• Move the magnet a little from its position

• Heat the magnet

• Tie the magnet to a wooden block

• Place the magnet in a plastic tub

What observation is made after the freely suspended magnet comes to rest?

• The magnet points towards the north-south direction

• The magnet points towards the east-west direction

• The magnet stops moving completely

• The magnet floats in the air

What is the next step after tying the bar magnet to a wooden block?

• Heat the wooden block

• Place the wooden block on a metal surface

• Suspend the wooden block in the air

• Place the wooden block in a plastic tub half filled with water

What conclusion can be drawn from the experiment involving the magnet and wooden block in water?

• A freely suspended or static magnet in water always points towards the north-south direction

• A freely suspended or static magnet in water always points towards the east-west direction

• A freely suspended or static magnet in water always floats

• A freely suspended or static magnet in water always sinks
