The magnetic field declination at your location is 7.00 degrees east of north and the inclination is 27.0 degrees. If the magnitude of the Earth's magnetic field is 0.0600 mT at your location, how much current must flow in a long vertical wire placed 1.00 cm from the compass in order to make the compass point in the direction of geographic north? (Ignore the size of the compass compared to its distance from the wire and assume the compass is in a uniform magnetic field given by the value of the field 1.00 cm from the wire.)
