Question

The pattern of the magnetic field produced inside a current carrying solenoid is :

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The Correct Option is C

Step 1: Understanding the Solenoid's Magnetic Field:
A solenoid, a coil of wire, generates a magnetic field when current passes through it. This field exhibits distinct patterns both internally and externally.

Step 2: Magnetic Field Within the Solenoid:
Internally, the magnetic field lines are straight, parallel, and densely packed, signifying a strong and uniform field. This uniformity arises from the summation of individual fields from each coil loop.

Step 3: Magnetic Field External to the Solenoid:
Externally, the magnetic field lines curve to form loops. This pattern mirrors the field around a bar magnet, with lines extending between its poles.

Step 4: Field Pattern Summary:
- Inside: Uniform field, depicted by straight, parallel lines.
- Outside: Looping field, analogous to a bar magnet's field.

Step 5: Accurate Representation:
A correct diagram will show parallel lines within the solenoid, indicating uniformity, and curved lines outside, illustrating the looping field. This pattern is characteristic of a current-carrying solenoid.
