In Ayurveda, herbs or plant parts are dried in the shade to allow excess water to evaporate, preserving the important medicinal components of the plants. NCERT Book Curiosity Science Class 6 Class 6 Science NCERT Chapter 9
Magnets in electric motors create a magnetic field that interacts with the current-carrying coil, producing rotational motion. This interaction between the magnetic field and electric current is fundamental to the motor’s operation.
The Earth’s magnetic field is a natural magnetic field generated by the movement of molten iron in the Earth’s outer core. It protects us from solar radiation and aids in navigation using compasses.
Temperature affects magnetism by altering the alignment of magnetic domains. At high temperatures, thermal energy disrupts this alignment, reducing a magnet’s strength. Extremely high temperatures can even demagnetize a material.
One water body in India that contains common salt is Sambhar Lake in Rajasthan. Chapter 9 Methods of Separation in Everyday Life NCERT Book Curiosity Science Class 6
In a compass, a magnetized needle aligns itself with the Earth’s magnetic field, pointing toward the magnetic north. This allows users to determine direction relative to the Earth’s magnetic poles.
Magnets are used in various everyday applications, such as in fridge magnets, compasses, electric motors, speakers, and magnetic locks. They also play a critical role in industrial machinery and medical devices.
A permanent magnet has a constant magnetic field and does not require electricity. An electromagnet, however, needs an electric current to generate its magnetic field, and its strength can be controlled.
The strength of an electromagnet can be increased by increasing the electric current, adding more turns to the wire coil, or using a core with better magnetic properties, like soft iron.
