Question

Identify the type of magnetic fields represented by the magnetic field lines given below and name the type of conductors which can produce them.

Answer 1

AnswEr :-

We are Given with two picture based questions the Question is to find the type of magnetic field and name the type of conductors.

Case 1 :-

The picture ( A ) is A Magnetic field produced on a Current Carrying Circular Loop.

in this case the it appears to be a straight line on centre and concentric and edges where magnetic field is high.

Case 2 :-

In the Picture ( B ) the magnetic field is Uniform Magnetic field This type of Magnetic field is produced on Inside the Bar Magnet.

The Magnetic field in every single point is equal and uniform like a straight line.

$\boxed{ \bold{ \red{★Hence \: Stated}{} }{} }{}$

Answer 2

Answer:

(A)External Magnetic field lines produced by a circular loop in a uniform magnetic field.

(b)They are internal magnetic fields produced by solenoids in uniform magnetic fields.

Explanation:

(A)Inside the current-carrying circular loop the magnetic field lines are concentric circles. The right-hand thumb rule can be used to determine the direction of the magnetic field in the circular loop.

• The magnetic field lines are straight at the center of the circular loop.
• Magnetic field lines in the same direction are produced by each current-carrying portion of a circular loop.
• The magnetic field at the center of a circular coil is perpendicular to the coil's location. That is, along the coil's axis.

(B) When an electric current is sent through a solenoid, a long, thin loop of wire, frequently coiled around a metallic core, produces a magnetic field. Solenoids are significant because they have the ability to generate regulated magnetic fields and can be utilized as electromagnets.

• The field lines created by individual loops join/augment each other to produce a homogeneous magnetic field. Solenoid carries the same amount of current because the current is running through the loops.
