Q
Q: What happens to the magnetic field when the current in a wire is reversed? (2023)
Solution:
When the current in a wire is reversed, the direction of the magnetic field also reverses.
Steps: 5
Show Steps
Step 1: Understand that a wire carrying electric current creates a magnetic field around it.
Step 2: Know that the direction of the magnetic field is determined by the direction of the current flowing through the wire.
Step 3: When the current in the wire is reversed, it means the flow of electricity changes direction.
Step 4: Since the magnetic field direction depends on the current direction, reversing the current will also reverse the magnetic field direction.
Step 5: Therefore, when the current is reversed, the magnetic field also reverses.
