You have learned that a charge moving in an magnetic field can experience a
magnetic force. Remarkably, anytime that a charged particle moves that particle
produces its own magnetic field! The image below of magnetic compasses forming
a circle around a current-carrying wire demonstrates the shape of the magnetic
field. The magnetic field lines forms concentric circles around that wire. The
strength of the field decreases with increasing distance away from the wire.
If the current in the wire is 1.97A, what is the magnitude of the magnitude of the
magnetic field (in µT, or micro-Tesla) a distance of 0.74m away from the wire?
Note: It is understood that the unit of your answer is in uT, however do not
explicitly include units in your answer. Enter only a number. If you do enter a unit,
your answer will be counted wrong.
