Flashcards in ME6 - Magnets and magnetic field Deck (16):
1

What do magnetics produce?

Magnetic fields

2

What do all magnets have?

- Two poles (north and south)
- The poles are the strongest part of a magnet

3

What is a magnetic field?

A region where magnetic materials (iron) experience a force

4

What do magnetic field lines show?

The size and the direction of the magnetic fields - always point from north to south

5

What happens if you place the north and south poles of two permanent magnets near each other?

It creates a uniform field between the two magnets (straight lines going from north to south)

6

What can you use to look at magnetic field lines?

Compasses and ion fillings

7

What do compasses and iron fillings do to make us see the magnetic fields?

Align themselves with the magnetic field

8

How can see the magnetic field with iron fillings?

Put a magnet(s) under a piece of paper and scatter the iron fillings on top

9

How can you see the magnetic field lines with compasses?

Use more than one compass/ a compass and move it around a magnet (trace the pathway on a piece of paper)

10

What do magnets affect?

Any magnetic materials or other magnets

11

Likes poles...

Repel

12

Opposite poles...

Attract

13

What happens when a magnet is brought near a magnetic material?

That material acts as a magnet (the magnetism has been induced by the original magnet)

14

What happens the closer the magnet and magnetic material get?

The stronger the induced magnetism will be

15

Far from the magnet...

Little induced magnetism

16

Close to the magnet...

Magnetism induced
