Introduction

What are the maximum number of pins you can link using a magnet. How does this number change when you add a magnet?

    • Be careful about the sharp ends of the nails and paper pins.

    • There's no need to open the safety pins; beware of them if they open out.

  1. Download or copy the table in your notebook.
    • Download or copy the table in your notebook.

    • Fill the prediction column. Eg: Predict how many paper pins one magnet can hold and note it down in the table.

  2. Take one magnet and observe how many paper pins it can hold one below the other. Now add one more magnet and find out if it can hold more or less number of paper pins one below the other. Repeat the above procedure for as many magnets (say 4 in total) you have.
    • Take one magnet and observe how many paper pins it can hold one below the other.

    • Repeat the above procedure for as many magnets (say 4 in total) you have.

    • Record your observations in the observation post-experiment column of the table.

  3. Repeat Step 2 for different materials like nuts, nails and safety pins. Repeat Step 2 for different materials like nuts, nails and safety pins. Repeat Step 2 for different materials like nuts, nails and safety pins.
    • Repeat Step 2 for different materials like nuts, nails and safety pins.

    • If the magnet is old, it could have lost its strength over time.

    • The ferromagnetic material (nuts, nails etc) is too heavy compared to the magnet.

    • Take one magnet and try attracting as many number of ferromagnetic materials as you can (not necessarily one below the other) and measure the total mass it can hold.

    • Find out how many pins/nuts/nails the magnet can hold over its entire surface area. Is it any different from holding it one below the other?

    • Use these magnets to attract different materials like wood, plastic, cloth piece etc and observe what happens.
