15. Magnetic Fields

16. What’s a field? Field is a word we all understand – it’s a place with lots of grass! But scientists also use the word ‘field’ with another meaning. A field is an area where a force acts. So, a magnetic field is the area where a magnet could attract something. Can you think of any other sort of field in science?

17. What does a magnetic field look like? Well, we can’t see it for a start, but... Small particles of iron filings are pushed into patterns by a magnetic field. If we sprinkle iron filings on a piece of paper over a magnet we can see... The lines of force are very close together here – the field is very strong. The lines of force are further apart here – the field is weaker. A line of force links one pole of a magnet to the other pole.

18. Demonstrating Magnetic Fields Demonstrate the magnetic field around a bar magnet using iron fillings in a plastic container. A 3d magnetic field can also be shown here. Use a transparent compass to demonstrate that the field lines come out of the N pole and go into the S pole.

19. Electromagnetism :Magnetic Fields  What does the magnetic field around a bar magnet look like ? [shape and direction]. N S Strongest at poles Weaker further away

20. 08/08/2015 N S Magnetic fields

21. The rule about directions... The magnetic force acts in a direction. The arrowheads on this diagram show you the way the needle of a compass point would go if it was free to move. You can see that the magnetic force runs from the north pole to the south pole of the magnet.

22. 1. Iron filings can be used to show the shape of the magnetic field. 2.Magnetic field lines always go out of the north pole. 3. Magnetic field lines come out of both ends of a magnet. 4.Magnetic materials placed in the magnetic field will be attracted towards the magnet. True or false? TRUE FALSE TRUE

23. Magnetic Fields - Summary 1. When two like poles (e.g. two North poles or 2 South poles) are put together, they repel each other. 2. When two unlike poles (e.g. a North and a South pole) are put together, they attract each other. 3. Scattering iron filings around the bar magnets allows us to see the lines of force of the magnetic field.

25. Making a Magnet Try one of these experiments 08/08/2015

26. Making a magnet It is possible to make a magnet by magnetising a material which can be attracted to a magnet, e.g. a paperclip. This can be done by: Stroking a magnet along the paperclip from one end to the other and then starting from the same place, repeat the movement. The more times this is done, the more magnetic the clip becomes. Holding a nail in a magnetic field and hitting it with a hammer. Putting a magnetic material in strong magnetic field. Watch this video to help you.
