Q
Q: What is the effect of reversing the direction of current in a loop of wire on the magnetic field? (2019)
Solution:
Reversing the direction of current in a loop of wire reverses the direction of the magnetic field produced by the loop.
Steps: 5
Show Steps
Step 1: Understand that a loop of wire carries an electric current.
Step 2: Know that when current flows through the wire, it creates a magnetic field around the loop.
Step 3: Remember that the direction of the magnetic field depends on the direction of the current.
Step 4: If you reverse the direction of the current in the loop, the magnetic field will also change direction.
Step 5: Conclude that reversing the current in the loop reverses the magnetic field direction.
