Key Topics in Chapter 10: Fun with Magnets (मुख्य विषय)
1. What is a Magnet? (चुम्बक क्या है?)
A magnet is a material that produces a magnetic field and attracts certain metals like iron (लोहा), nickel (निकेल), and cobalt (कोबाल्ट). Magnets can either attract or repel other magnets, depending on their poles.
- Example (उदाहरण): The attraction of a magnet to a paperclip or a nail (चुम्बक का कील या कागज की क्लिप को आकर्षित करना) demonstrates the basic property of magnets.
2. Properties of Magnets (चुम्बकों के गुण)
Magnets have several important properties, which make them useful in various applications:
- Attraction and Repulsion (आकर्षण और प्रतिकार): Magnets can attract or repel other magnets and materials.
- Poles (ध्रुव): A magnet has two poles – the North Pole (उत्तर ध्रुव) and the South Pole (दक्षिण ध्रुव).
- Direction (दिशा): A freely suspended magnet always aligns in a north-south direction.
3. Types of Magnets (चुम्बकों के प्रकार)
There are three main types of magnets:
- Natural Magnets (प्राकृतिक चुम्बक): These magnets occur naturally in nature. The most common example is lodestone (लोड़स्टोन), which is a naturally magnetized mineral.
- Artificial Magnets (कृत्रिम चुम्बक): These are man-made magnets and include bar magnets, horseshoe magnets, and disc magnets.
- Electromagnets (इलेक्ट्रोमैग्नेट): These are temporary magnets created by passing electric current through a wire wound around a magnetic material like iron.
4. Magnetic Poles (चुम्बकीय ध्रुव)
Every magnet has two poles:
- North Pole (उत्तर ध्रुव): The end of the magnet that points towards the Earth’s magnetic north.
- South Pole (दक्षिण ध्रुव): The end of the magnet that points towards the Earth’s magnetic south.
Like poles repel, and opposite poles attract. This means that two north poles or two south poles will repel each other, while a north pole and a south pole will attract each other.
5. Magnetic Compass (चुम्बकीय कम्पास)
A magnetic compass is an instrument used to find directions. It consists of a small magnet balanced on a pin. The needle of the compass always aligns with the Earth’s magnetic field, pointing towards the north and south poles.
- Use of Compass (कम्पास का उपयोग): It helps in navigation and finding directions, especially in ships, airplanes, and trekking.
6. Uses of Magnets (चुम्बकों के उपयोग)
Magnets have a wide range of uses in our daily lives. Some common applications include:
- In Electronics (इलेक्ट्रॉनिक्स में): Magnets are used in devices like speakers, microphones, and electric motors.
- In Medicine (चिकित्सा में): MRI machines (मैग्नेटिक रेजोनेंस इमेजिंग) use strong magnets to generate detailed images of the inside of the body.
- In Transportation (परिवहन में): Magnets are used in maglev trains (मैग्नेटिक लिविटेशन ट्रेन) that float on a magnetic field and move at high speeds.
- In Storage Devices (स्टोरेज उपकरणों में): Hard drives and credit card strips use magnets to store data.

FAQs on Fun with Magnets (RBSE Class 6 Science Chapter 10)
Q1: What are the two types of poles in a magnet? (चुम्बक में दो प्रकार के ध्रुव क्या होते हैं?)
The two types of poles in a magnet are the North Pole (उत्तर ध्रुव) and the South Pole (दक्षिण ध्रुव).
Q2: What happens when like poles of two magnets are brought together? (यदि दो चुम्बकों के समान ध्रुव एक साथ लाए जाएं, तो क्या होता है?)
Like poles of two magnets repel each other (समान ध्रुव एक-दूसरे को धक्का देते हैं).
Q3: What is an electromagnet? (इलेक्ट्रोमैग्नेट क्या है?)
A: An electromagnet is a temporary magnet created by passing electric current through a wire wound around a magnetic material.
Q4: What is the use of a magnetic compass? (चुम्बकीय कम्पास का उपयोग क्या है?)
A: A magnetic compass is used to find directions by aligning with the Earth’s magnetic field.
Q5: Where are magnets used in daily life? (चुम्बकों का उपयोग दैनिक जीवन में कहाँ किया जाता है?)
A: Magnets are used in electronic devices, medical equipment (like MRI machines), transportation systems, and data storage devices.
