What Magnets Are & Drawing Magnetic Field Lines
This lesson covers:
- The different types of magnets
- How to draw magnetic field lines
- What the magnetic field lines can tell us about the magnet
electric / magnetic
A magnet is any material or object that produces a field.
|
Which of the following are examples of magnets?
(Select all that apply)
A horseshoe magnet
A charged rod
A bar magnet
The Earth
|
The above diagram shows a bar magnet and its magnetic field lines.
The arrows on the field lines always point:
Out from the north and into the south
Out from the south and into the north
|
thickness / colour / density
The strength of a magnetic field is shown by the of the magnetic field lines.
|
Magnetic field lines can show:
(Select all that apply)
Whether two magnets would attract or repel
The strength of the magnet at a particular point
The direction that a small compass would point at that point
The density of the material
|
The above diagrams shows two regions of a bar magnet, labelled A and B.
Which region has a stronger magnetic field and why?
Region A because the field lines are further apart
Region A because the field lines are closer together
Region B because the field lines are further apart
Region B because the field lines are closer together
|
The above diagram shows two bar magnets which are:
Repelling each other
Attracting each other
|
The above shows two bar magnets.
The poles of the two magnets are labelled A and B.
Which of the following is correct?
Pole A is north and pole B is south
Pole A is south and pole B is north
Pole A is north and pole B is north
Pole A is south and pole B is south
