Q1: Using 3–4 different magnets, try to lift steel pins or U-clips and check which magnet picks up the largest number of pins. Discuss with your friends why different magnets might have picked up different numbers of pins.

Answer:

Experiment Steps:

• Gather 3-4 magnets of various size and shape (including bar magnet, ring magnet, disc magnet, and U-shaped magnet).
• On a table, drop some piles of steel pins or U -clips.
• Take each magnet in turn and use it to measure how many pins it can pick up at a time with the magnetic pile.
• Repetitively determine the number and jot in your notebook.

Sample Observations Table:

Observation points:

1. Various magnets hold more or fewer pins due to the differences in their strengths.
2. The power of the magnet depends on the size, material, and more so on the shape of the magnet. U-shaped magnets tend to have more powerful poles near one another, thus they can generate a more magnetic field at the opposite ends.
3. Some of the magnets might be old and therefore unable to hold their strength so they would pick-up fewer pins.
4. The area close to the poles of the magnet is the strongest and therefore attempt to pick the pins using those areas.

Conclusion:
The magnet that is largest, newest, or has a design that brings both poles close together (like a U-magnet) will generally pick up the most pins.

Q2: Make a toy ‘Hopping Frog’ as a combined class activity with the help of your teacher. For constructing the toy, fix ring magnets in an alternate North-South fashion along the length of a scale using glue (Fig. 4.18a). Paint a frog on paper, cut along the outline and glue a ring magnet at its base. Take a transparent, flexible plastic strip (Fig. 4.18a) of a smaller size and glue it to the ring magnet which is attached to the frog. When you slide the plastic strip (with frog) over the scale (Fig. 4.18b), you can observe the frog hopping

Answer:

Construction Steps:

1. Stick ring magnets to a scale in an alternate North-South pattern using glue.
2. Trace and cut the picture of a frog on paper and fix a ring magnet under the frog with glue.
3. To the frog base (with the magnet) attach a small flexible strip of plastic.
4. Put the frog onto the magnet scale and slide it--and when you move the strip, the frog will hop along over the magnets.

Why does the frog hop?

The magnets repel each other if like poles face, pushing the frog magnet upward a little, making it “hop.”

Q3. Find out about the Maglev Train and try to make its model.

Answer:

Maglev Trains:

1. Maglev is short for Magnetic Levitation train.
2. Such trains hover on the tracks with the help of strong magnets. The train is hanging above the track by means of one set of magnets, and a different set of magnets propels it.
3. Since there is no rubbing of wheels on the track, there is practically no friction hence Maglev trains can move quite swiftly and run on the track smoothly.

Steps to make a simple maglev model at home:

• Cut several strong bar magnets and glue them along a piece of cardboard to replicate a ”track” (like North, South, North, South).
• Take a little plastic slab and put 2 bar magnets (magnets with both poles pointing at the track magnets) under it.
• Put the slab back to the track it should repel and lift and slide nicely.
• Push gently & with one smooth motion, it glides. (Note: Much strong neodymium magnets work far better!)

Q4: Try to find out why there is a need to make magnets of different shapes.

Answer:

Magnets come in various shapes as magnets are applied for various purposes:

1. Bar magnets: Suitable for the use in the laboratory, in the compass and some general use.
2. U-shaped/Horseshoe magnets: Two of whose poles are right next to each other and the magnetic field is stronger at the gap—great for lifting heavy loads.
3. Disc magnets: Use in small areas, small speakers, bags and other complicated tiny gadgets.
4. Ring magnets: Used where you need a hole in the center like on some motors.
5. Cylindrical magnets: In use by devices needing a strong long field such as MRI machines.

Q6: Collect information related to the use of magnets in the field of medicine.

Answer:

Magnets play an essential role in medicine, due to a number of reasons:

1. MRI (Magnetic Resonance Imaging): Makes detailed pictures of the inside of the body (such as the brain, joints, and heart) using powerful magnets and radio waves, instead of harmful X-ray.
2. Magnetic therapy: Most individuals have magnet therapy where they apply magnets to alleviate pain.
3. Extraction procedures: In selected instances, physicians apply a small magnet to extract metal splinters or particles, or from eyes or cuts.
4. Medical sensors - Certain devices have small magnets to monitor the position of any body part (e.g. in certain hearing aid or in some prosthetics).

Exploring Magnets Class 6 Chapter 4 - Topics

Class 6 Science Chapter 4- Exploring Magnets teaches students the fascinating nature and play of the magnets. The chapter enables a learner to know about the working of the magnets, how these magnets interact with various materials, and what these magnets are utilized in our day-to-day life. It forms the basis of important scientific principles in a more casual way and in a form that is intuitive.

4.1 Magnetic and Non-magnetic Materials

This topic assists students to distinguish the materials that are and are not attracted to magnets. Such as iron, cobalt, nickel in materials can be held magnetized, whereas plastic, wood and glass are not magnetic.

4.2 Poles of Magnet

This part brings in the two poles of a magnet North Pole, and South Pole where the magnetic force is maximum. It also gives the interaction between these poles.

4.3 Finding Directions

Students learn how a suspended magnet aligns itself in the north-south direction. This property is used in magnetic compasses for navigation.

4.4 Attraction and Repulsion between Magnets

This section describes the interaction of magnets when they are brought near to one another. When like poles are brought into contact they repel (push); when unlike they attract (pull).

4.5 Fun with Magnets

The activities in this subject are easy and interesting, such as how to rub a magnet at home and create a magnet, how to see the magnetic effect in everyday life.

Approach to solve the Class 6 Science Chapter 4 Exploring magnets

The concepts that a student should have a clear picture on when approaching the solving of Class 6 Science Chapter 4 Exploring Magnets successfully include magnetic and non-magnetic materials, the idea of magnetic poles, attraction and repulsion and the practical applications of magnets. Conceptual clarity will be enhanced by slowly going through the textbook section by section and doing the recommended exercises. Learners are expected also to notice how magnets work in the real life to apply the theory to practice. When attempting questions, concentrate on writing uncomplicated and correct answers. Using NCERT solutions to tackle tricky or ambiguous questions can also assist you in revising and gaining confidence prior to exams.
