A straight wire carrying a current of 48 A lies along the axis of a 4.9 cm diameter solenoid. The solenoid is 55 cm long and has 250 turns carrying a current of 5.0 A. 1)What is the magnitude of the magnetic field 1.3 cm from the wire? (in mT) 2)Estimate the magnitude of the magnetic field 3.4 cm from the wire. (in mT) I know that B of the wire is 0.196mT and the B of the solenoid is 1.570mT but I'm not sure where to go after this. PLEASE HELP!
