Question

Which of the following is a wrong statement?

A)Magnetic field inside a solenoid is uniform.

B)A current carrying solenoid behave like a bar magnet with fixed polarity at its ends.

C)Magnitude of magnetic field inside the solenoid is directly proportional to the current flowing through the solenoid.

D)Magnitude of the magnetic field inside the solenoid is directly proportional to the number of turns on the solenoid.​

Answer 1

I think, A is wrong, but i am not quite sure,

so spare me if i am wrong

i think, inside a solenoid,

there lines of magnetic field are close in the middle area, while a little bit farther in the region near it ends

HOPE IT'S RIGHT

Cheers,

Answer 2

Answer:

The strength of the magnetic field within the solenoid is inversely proportional to the current passing through it.

In physics, a long, narrow series circuit that is frequently wrapped around a metallic core is referred to as a solenoid. When an electric charge is sent through the solenoid, a magnetic field is created. Since they can produce regulated earth's magnetic field and be utilized as electromagnetic force, solenoids are significant.

Explanation:

a. A coil of insulated wire with several round turns that is tightly wound into a cylindrical shape. The magnetic flux inside the solenoid is uniform and is demonstrated by an equivalent applied electric field. These lines produced by the numerous solenoid loops link to or strengthen each other to form a homogenous magnetic field since each solenoid loop carries the very same flow of charge.

b. When a solenoid is conducting current, the magnetic field line pattern identically mirrors that of an electromagnet with constant polarity, or North and South poles at its ends, and it develops bar magnet-like directing and attracting qualities.

c. The includes high - level as well as the quantity of turns per unit length affect the magnetic field inside a solenoid. The field within the electromagnet is constant and does not depend on the diameter of the device, nor does it reflect on where it is located inside.

d. A solenoid's internal magnetic field is inversely proportional to the applied current and the inductance per unit length. The field within the solenoid is continuous and has no relationship to the diameter of the device as well as the position inside the device.
