"Interaction of Magnetic Poles" Magnet PPT

Description

"Interaction of Magnetic Poles" Magnet PPT

Part I: Magnetic Pole and Direction

Hang a bar magnet horizontally so that it can rotate freely in the horizontal direction. Observe the position where the magnet comes to rest and record it. Repeat this several times.

What did we discover by observing the hanging magnets?

A magnet that can rotate freely has one pole pointing south and the other pole pointing north when it is stationary.

Magnets have the property of indicating the north and south directions.

Do we need to modify the A, B, C, and D labels we gave to the magnetic poles in the last class? How should we modify them?

Use the hanging method to find the south and north poles of a magnet.

The letter S represents south and N represents north.

Interaction of magnetic poles PPT, Part 2: How magnetic poles interact with each other

We call two identical magnetic poles like poles, and different magnetic poles like poles.

How do magnetic poles interact with each other? Is there a simpler way to describe it?

When two magnets are brought close to each other, like poles repel each other and opposite poles attract each other.

Like poles repel each other, unlike poles attract each other.

For magnets of other shapes, can we find their north and south poles?

Hanging method

Approach a magnet with known north and south poles
