Q

What is a magnet?

A

Any material or object that produces magnetic field (i.e. bar & horse-shoe magnet & earth)

2
Q

What do all magnets have in common?

A
  • Have two poles (north & south)

- Surrounded by a magnetic field

3
Q

What are field lines?

A

Arrows u draw around your magnet from north pole to south Pole (represents magnetic fields)

4
Q

Advantages of representing a magnetic with field lines

A
  • Shows where the field is & which direction it is acting in

- Shows relative strength of field in different places

5
Q

How can we tell if a magnetic field is much stronger?

A

The field lines will be closer together

6
Q

How can we find the poles & field lines using a compass?

A

In compass there’s bar magnet - always line up with the field lines or whatever magnetic field its put in
Always points towards south pole of a magnet
