Question 191 markMCQSection A

$Assertion (A) : The pattern of the magnetic field of a solenoid carrying a current is similar to that of a bar magnet. Reason (R) : The pattern of the magnetic field around a current carrying conductor is independent of the shape of the conductor.$

Magnetic Effects of Electric Current

Magnetic Field due to a Current in a Solenoid

Options

(A)

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

(B)

Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).

(C)

Assertion (A) is true, but Reason (R) is false.

(D)

Assertion (A) is false, but Reason (R) is true.

Official answer

The pattern of the magnetic field of a solenoid carrying a current is similar to that of a bar magnet. However, the pattern of the magnetic field around a current carrying conductor depends on the shape of the conductor.

Marking scheme

1. $1 mark$

Hint

$Recall the pattern of the magnetic field of a solenoid carrying a current and that of a bar magnet.$

Quick oral answer

$The pattern of the magnetic field of a solenoid carrying a current is similar to that of a bar magnet. However, the pattern of the magnetic field around a current carrying conductor depends on the shape of the conductor.$

Common mistakes

1. $thinking that the pattern of the magnetic field around a current carrying conductor is independent of the shape of the conductor$

Analysis and explanation

The assertion is true as the pattern of the magnetic field of a solenoid carrying a current is similar to that of a bar magnet. However, the reason is false as the pattern of the magnetic field around a current carrying conductor depends on the shape of the conductor.

Interesting facts

$The pattern of the magnetic field of a solenoid carrying a current is similar to that of a bar magnet.$
