A coil with many circular close turns of insulated copper wire (like a cylinder as shown above) is a solenoid. One end of such a solenoid behaves like the north pole and the other as a south pole. Therefore magnetic field due to current in the solenoid is similar to a bar magnet. A solenoid is an essential coil of wire that is used in electromagnets, inductors, antennas, valves, etc. The application of a solenoid differs in numerous types like medical, locking systems, industrial use, the bottom line and Automotive Solenoid Applications.

Imaginary lines which represents the magnetic field

0Thank You

Meghna Thapar 5 years ago

The magnetic field is an abstract entity that describes the influence of magnetic forces in a region. Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position. Because monopoles are not found to exist in nature, we also discuss alternate means to describe the field lines in the sections below. One useful analogy is the close connection between magnetic monopoles and electric charges. A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetized materials. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetized materials. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The definition of a magnetic field is a place in space near a magnet or an electric current where a physical field is created from a moving electric charge that creates force on another moving electric charge. An example of a magnetic field is the Earth's magnetic field. noun.

What will happen if we remove decomposers from naturw

Posted by Vision X 5 years ago

CBSE > Class 10 > Science

1 answers

Meghna Thapar 5 years ago

In the absence of decomposers in the environment, this breakdown will not occur and hence, the nutrients will not be released. Due to this, plants will not get sufficient nutrients. They perform a valuable service as Earth's cleanup crew. Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. Imagine what the world would look like! More importantly, decomposers make vital nutrients available to an ecosystem's primary producers—usually plants and algae.

Displacement reaction:-A + B-C → A-C + B,,When balancing a decomposition reaction, the number of moles should be equal on both sides. For example, in the equation NaCl gives you Na + Cl2, there is one mole of Na on both sides, but there is one mole of Cl on the left side and two moles on Cl on the right side.

How our blood gets deoxygeneted?

King?Adithya H. M.. 5 years ago

The ventricles are the two lower chambers of the heart. Blood empties into each ventricle from the atrium above, and then shoots out to where it needs to go. The right ventricle receives deoxygenated blood from the right atrium, then pumps the blood along to the lungs to get oxygen.

2Thank You

Deep Arshnoor 5 years ago

CO2 is a waste product of cellular respiration. This CO2 is transported in blood. This blood is called deoxygenated blood which is transported from the right atrium to the right ventricle which then goes to the lungs. From here the CO2 is absorbed from the blood by the alveoli and then the rest of the blood is called oxygenated blood.

According to Gandhiji , the British rule was established in India with the cooperation of Indians, and had survived only because of this cooperation. So time has arrived o withdraw cooperation to the British.
First World War added to the misery of the Indian people. Heavy taxes, high prices, famines and epidemics made people's life miserable.
Rowlatt Act invited large scale protests throughout the country.
Jallianwala Bagh Massacre and the injustice done to Punjab made Indians angry which need to be avenged.
To restore the status of the ruler of Turkey.
To bring Swaraj or Self Rule to India.
Mahatma Gandhi declared that the main objectives of the non cooperation movement were :
To cripple the British administration and make them realize that they cannot function without the actual support of the Indians.
To avenge the wrong done by the Government in Punjab (Jallianwala Bagh Massacre) in a non violent way.
To bring about unity among the people. To inculcate a sense of nationalism.
