describe the method of making magent by single touch
Answers
Answer:
Single Touch Method
Take a small iron bar of length AB and place it on the table. Now, take a bar magnet and select one of its pole. Move the north pole of the bar magnet along the iron bar from A to B. When you reach the end point B, lift your bar magnet and move it along the same direction again. Repeat this process several times.
You will observe that after sometime the iron bar gets magnetised with one of the end acting as the north pole and another end acting as the south pole. You can also test the iron bar for magnetic properties by bringing its north pole closer to the north pole of the bar magnet. You will observe that the two repel each other. Now. bring some iron filings near the magnetised iron bar. You will observe that these will stick to the bar.
