Question: In a solenoid carrying current, what is the direction of the magnetic field inside the solenoid according to Ampere\'s Law?

Options:

Correct Answer: From north to south

Solution:

The magnetic field inside a solenoid is directed from the north pole to the south pole of the solenoid.

In a solenoid carrying current, what is the direction of the magnetic field inside the solenoid according to Ampere's Law?

In a solenoid carrying current, what is the direction of the magnetic field inside the solenoid according to Ampere's Law?

Step 1: Understand what a solenoid is. A solenoid is a coil of wire that creates a magnetic field when an electric current passes through it.
Step 2: Identify the direction of the current flowing through the solenoid. The direction of the current is important for determining the magnetic field.
Step 3: Use the right-hand rule to find the direction of the magnetic field. Point your thumb in the direction of the current, and curl your fingers around the solenoid.
Step 4: Notice that your fingers will curl in the direction of the magnetic field lines inside the solenoid.
Step 5: Recognize that the magnetic field inside the solenoid runs from the north pole to the south pole of the solenoid.

Ampere's Law – Ampere's Law relates the integrated magnetic field around a closed loop to the electric current passing through the loop.
Direction of Magnetic Field – The direction of the magnetic field inside a solenoid is determined by the right-hand rule, where the fingers curl in the direction of current flow and the thumb points in the direction of the magnetic field.
