What happens to the magnetic field when the current in a solenoid is reversed? (2023)

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: Know that the direction of the magnetic field is determined by the direction of the current flowing through the solenoid.
Step 3: When the current flows in one direction, the magnetic field has a specific direction (for example, from the north to the south pole).
Step 4: If you reverse the current, it means the flow of electricity changes direction.
Step 5: When the current is reversed, the magnetic field also changes direction, meaning it will now point in the opposite way.
