Question
A = Aĥ JA = Aîn = Magnetic moment T. m m e P I=-|I| e" Loop area A I=+|I| = T. Απρ Figure 4: 5. Since the magnitude of the magnetic moment is defined as u I A[its direction being along the area vector] it follows that a circulating positive charge [see figure 4] constitutes a magnetic dipole given by[T is the period of the cycle, and L = 7 x p = 7 × mi = mvrî is the angular momentum. Notice that L = m × J = mr × 4 = m dà 2 dt since dA = 27 × dr]: lal (+L) in the same direction as L if q > 0 dTab n = 2m jī = Ià = An = T (rp²)n (True, False) = I Aî = 2m L (-L) in the opposite direction to L if q < 0 2m you will see in chapter 28 that the paramagnetic materials develop dipoles in the same direction as applied magnetic field [they get attracted to the magnet] while diamagnetic materials develop dipole in opposite direction to applied magnetic field[they are repelled by the magnet].
