Q
Q: If the current in a wire is reversed, what happens to the direction of the magnetic field around the wire?
Solution:
Reversing the current in a wire reverses the direction of the magnetic field around it.
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: If the current in the wire is reversed, it means the flow of electricity changes direction.
Step 4: When the current changes direction, the magnetic field also changes direction.
Step 5: Therefore, reversing the current in the wire reverses the direction of the magnetic field around it.
