Q
Q: If the current in a wire is doubled, how does the magnetic field at a point 1 meter away change?
Solution:
The magnetic field is directly proportional to the current, so it doubles.
Steps: 4
Show Steps
Step 1: Understand that a wire carrying current creates a magnetic field around it.
Step 2: Know that the strength of the magnetic field depends on the amount of current flowing through the wire.
Step 3: Remember that if the current is doubled, the magnetic field strength also changes.
Step 4: Since the magnetic field is directly proportional to the current, if the current is doubled, the magnetic field will also double.
