At large distances, a bar magnet acts like the magnetic dipole created by a current carrying loop. Imagine such a magnet is oriented as shown. The field strength at a point 10 cm from the magnet along the dipole axis is 5.0 ?T, where 10 cm >> the size of the magnet. The field strength is calculated in your book for a current carrying loop and the dipole moment of such a loop is discussed. Look up the discussion and answer the following:

a) What is the magnetic dipole moment of the bar?

b) What is the on-axis field strength 15 cm from the magnet?
