1) Consider a long, straight wire with current I running through it. You measure the magnetic field to be B at a distance d from the wire.

a. What will the magnetic field at d be if you triple the current in the wire?

b. What will the magnetic field at 4d be, assuming the current in the wire is dialed back down to I?
