A magnetic dipole of magnetic moment M , is freely suspended in a magnetic field of induction B . The minimum and maximum value of potential energy of the dipole, respectively are
Options
- A- MB ,+ MB
- B0, MB
- C0,2 MB
- DMB , 0
Correct answer
A. - MB ,+ MB
Step-by-step solution
The potential energy of the magnetic dipole is given by U =- MB Where is the angle between M and B For =0^ , U =- MB ^ =- MB (Minimum) For =180^ , U =- MB 180^ = MB (Maximum)
