Question

Assertion: Magnetic field is stronger at a point which is closer to the conductor and goes on decreasing on moving away from the conductor. Reason : Magnetic field produced by a straight conductor is inversely proportional to distance

Answer 1

Assertion is True,

Assertion : The magnetic field is stronger at a point which is nearer to the conductor and goes on decreasing on moving away from the conductor. Reason : The magnetic field B produced by a straight current carrying wire is inversely proportional to the distance from the wire.

Magnetic Field:

• A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents,[1]: ch1 [2] and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.[1]: ch13 [3]: 278  A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets.

• In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment.

• Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, it is described mathematically by a function assigning a vector to each point of space, called a vector field.

Answer 2

Answer:

(a) Both assertion and reason is true and reason is the correct explanantion of Assertion

Explanation

Since both above statements are true The reason that we see that the magnetic field produced is inversely proportional to the distance from the wire hence the assertion can be concluded, hence both statements are correct and reason correclty explains Assertion..
