A current in a long, straight wire produces a magnetic field of 10.0T at 4.00cm from the wire.

Part A

What is the magnetic-field strength 8.00cm from the wire? (Answer the question without finding the current.)

Part B

How far from the wire will the field be 3.00 T? (Answer the question without finding the current.)

Part C

If the current were doubled, what would the field be 4.00cm from the wire ? (Answer the question without finding the current.)
