Magnetic induction in Playing With Magnets – Class 6 Science Experiment

Chapter Name: Playing With Magnets

Activity Name: Magnetic induction in Playing With Magnets

Activity Description:

The experiment explores the concept of magnetic induction using a safety pin, an alpin (a type of pin), and a bar magnet. It aims to demonstrate how the presence of a magnet can induce magnetic properties in another object.

Required Items:

• Safety pin
• Alpin (pin)
• Bar magnet

Step by Step Procedure:

1. Take a safety pin and bring it close to an alpin. Observe whether the safety pin attracts the alpin.
2. Bring the safety pin close to one pole of a bar magnet and observe how it gets attached to the magnet.
3. Take an alpin and touch it to the safety pin.
4. Observe whether the safety pin attracts the alpin.
5. Hold a bar magnet in one hand and a safety pin in the other hand, keeping them close to each other but not in contact.
6. Ask your friend to bring an alpin and touch it to the safety pin.
7. Observe whether the alpin sticks to the safety pin.

Experiment Observations:

1. When the safety pin is brought close to the alpin without any other magnetic influence, it may or may not attract the alpin, depending on its magnetic properties.
2. When the safety pin is brought close to one pole of a bar magnet, it gets attached to the magnet.
3. When an alpin is touched to the safety pin after it has been in contact with the bar magnet, the safety pin may attract the alpin.
4. When the bar magnet and the safety pin are held close to each other but not in contact, and an alpin is touched to the safety pin, the alpin sticks to the safety pin.

Precautions:

• Handle the bar magnet and safety pin with care to avoid any injuries.
• Ensure that the safety pin is not forcefully pressed against the bar magnet to avoid damaging the pin or the magnet.
• Be cautious while handling the alpin to prevent accidental pricks.

Lesson Learnt from Experiment:

The experiment demonstrates the concept of magnetic induction. When a safety pin is brought close to a bar magnet, it can acquire magnetic properties and behave like a magnet.

This is known as magnetic induction, where a magnetic substance becomes magnetized due to the presence of a nearby magnet. The experiment also highlights that the magnetic induction effect persists even when the safety pin and the bar magnet are not in direct contact.
