Directions: In the following questions, a statement of assertion (A) ...
The magnetic field produced depends directly on the current flowing through the circular coil. If the number of turns of the coil increases then the current flowing in a coil also increases and hence the magnetic field will increase with increase in the number of turns.

Directions: In the following questions, a statement of assertion (A) ...
Assertion: The strength of the magnetic field produced at the center of a current carrying circular coil increases on increasing the current flowing through the coil.
Reason: Magnetic field strength is inversely proportional to the current flowing in the coil.
Explanation:
The assertion states that the strength of the magnetic field produced at the center of a current carrying circular coil increases when the current flowing through the coil increases. Let's analyze this statement and its reason.
Understanding the Assertion:
1. When a current flows through a circular coil, a magnetic field is produced around it.
2. The strength of the magnetic field at the center of the coil is determined by the amount of current flowing through it.
3. Increasing the current flowing through the coil will result in a stronger magnetic field.
Understanding the Reason:
1. The reason states that magnetic field strength is inversely proportional to the current flowing in the coil.
2. In other words, as the current increases, the magnetic field strength decreases.
Evaluating the Assertion and Reason:
The reason contradicts the assertion, as it states that increasing the current will result in a decrease in magnetic field strength. Therefore, the reason is false.
Conclusion:
The assertion is true, as increasing the current flowing through a circular coil does result in a stronger magnetic field at the center. However, the reason provided is false, as magnetic field strength is directly proportional to the current flowing in the coil. Therefore, the correct answer is option (c) - Assertion (A) is true, but reason (R) is false.
