Magnetic Fields and Field Lines

Flashcards covering key concepts about magnets and magnetic fields as presented in the lecture.

What are the two poles of a magnet called?

North and South poles.

What do field lines represent in the context of magnets?

They represent the direction and strength of the magnetic field around a magnet.

How should field lines be drawn in relation to the poles of a magnet?

Field lines are drawn from the North Pole to the South Pole.

What indicates a stronger magnetic field in a field line diagram?

The density of the field lines; closer lines indicate a stronger field.

Which direction does a compass needle point when placed in a magnetic field?

Towards the South Pole of the magnet.

What happens when the North poles of two magnets are brought together?

They repel each other.

What will occur when a North pole and a South pole of two magnets are brought together?

They will attract each other.

What common shape is often associated with magnets?

Bar magnet.

Can magnetic field lines be visually seen in real life?

No, they cannot be seen, but their presence can be inferred using compasses.

What is one way to check if the arrows on field lines are drawn correctly?

Ensure the arrows go out from the North Pole and into the South Pole.
