A current in a long, straight wire produces a magnetic field of 14.0 µT at 2 centimeter from the wire.
A) Obtain the magnetic-field strength 4 centimeter from the wire?
B) Obtain how far from the wire will the field be 1.00 µT?
C) If the current were doubled, find what would the field be 2 centimeter from the wire?
