A Loop of Current-Carrying Wire Has a Magnetic Dipole Moment

question 19

Multiple Choice

A loop of current-carrying wire has a magnetic dipole moment of 5.0 * 10^-4 A.m².The moment initially is aligned with a 0.50-T magnetic field.To rotate the loop so its dipole moment is perpendicular to the field and hold it in that orientation, you must do work of:

• A)0 J
• B)2.5 * 10^-4 J
• C)-2.5* 10^-4 J
• D)1.0* 10^-3 J
• E)-1.0 *10^-3 J
