## FAQs on Ampere's Circuital Law Force Between 2 Parallel Wires & Solenoid Video Lecture - Physics Class 12 - NEET

 1. What is Ampere's circuital law?
Ans. Ampere's circuital law states that the magnetic field around a closed loop is proportional to the current passing through the loop. It quantifies the relationship between magnetic fields and electric currents.
 2. How does Ampere's circuital law help calculate the force between two parallel wires?
Ans. Ampere's circuital law can be used to calculate the magnetic field created by one wire and then use the principle of superposition to calculate the total magnetic field between two parallel wires. By applying the right-hand rule, the force between the wires can be determined using the magnetic field and the current flowing through the wires.
 3. What is the force between two parallel wires according to Ampere's circuital law?
Ans. Ampere's circuital law can be used to determine that the force between two parallel wires carrying currents in the same direction is attractive, while it is repulsive when the currents are flowing in opposite directions. The force between the wires depends on the magnitude of the currents, the distance between the wires, and the permeability of the medium.
 4. How is Ampere's circuital law applicable to a solenoid?
Ans. Ampere's circuital law can be applied to a solenoid by considering the magnetic field created by the current flowing through its windings. By using Ampere's circuital law, the magnetic field inside the solenoid can be calculated. This allows for the determination of factors such as the magnetic field strength, the number of turns in the solenoid, and the current flowing through it.
 5. How does Ampere's circuital law relate to the force between two parallel wires and a solenoid?
Ans. Ampere's circuital law helps determine the magnetic field produced by the currents in both cases, i.e., between two parallel wires and inside a solenoid. By knowing the magnetic field, the force between the wires and the characteristics of the solenoid, such as its magnetic field strength and current, can be calculated. Ampere's circuital law provides a fundamental principle to understand the relationship between magnetic fields and electric currents in these systems.
