If the current in a coil is doubled, the magnetic field strength around the coil will?
Double
Halve
Remain the same
Increase by four times
The magnetic field strength around a coil is directly proportional to the current, so if the current is doubled, the magnetic field strength will also double.

Q
Q: If the current in a coil is doubled, the magnetic field strength around the coil will?
Solution: The magnetic field strength around a coil is directly proportional to the current, so if the current is doubled, the magnetic field strength will also double.
Steps: 4
Step 1: Understand that a coil creates a magnetic field when current flows through it.
Step 2: Know that the strength of the magnetic field depends on the amount of current flowing through the coil.
Step 3: Remember that if you double the current, you are increasing the flow of electricity through the coil.
Step 4: Since the magnetic field strength is directly related to the current, doubling the current will also double the magnetic field strength.
