A student makes a short electromagnet by winding 100 turns of wirearound a wooden cylinder of diameter d = 2.0 cm. The coil isconnected to a battery producing a current of 2.0 A in thewire.
(a) What is the magnetic moment of this device?
______ A·m2
(b) At what axial distance z d will the magnetic field of thisdipole have the magnitude 5.0 µT (approximately one-tenth that ofEarth's magnetic field)?
_______cm
Thanks for the help, feel free to check out my other Physicsquestions on this topic, I have another exam tomorrow so the helpwould be greatly appreciated!
