Bar magnets can be used in many ways within education to explain the facts about magnetism. One of the most important facts to teach students about magnets is about magnetic field. There are two separate experiments which can be used to highlight this: | ||||
Iron filings experiment |
||||
Things you will need:
|
||||
Step 1 – Place magnet under paperPlace a bar magnet underneath a piece of paper. Outline the bar magnet onto the piece of paper with the north and south clearly labelled. The purpose of the piece of paper is to prevent the magnets actually touching the iron filings. |
||||
Step 2 – Place iron filings onto paperScatter the iron filings onto the piece of paper to reveal the magnetic field of the bar magnet. |
||||
Compass experiment |
||||
Things you will need:
|
||||
Step 1 – Place magnet onto paperPlace the bar magnet at the bottom of the piece of paper with the compass placed an inch above its north pole. |
||||
Step 2 – Mark out north poleUse the pencil to mark a dot on the paper in front of the north pole of the compass pointer. |
||||
Step 3 – Continue until south pole is reachedMove the compass forward until the south pole of the compass needle points to the dot. Continue this process until the compass reaches the south pole of the compass. Then repeat again from the south pole to the north pole and then see what the finished pattern looks like. |
