Question

What is specified for each position \[Q_1,Q_2,\ldots,Q_6\] of magnetic needle \[Q\]?

Options

• Its own direction of magnetic moment \[m_Q\]

• Its own direction of magnetic moment \[m_P\]

• A different fixed position of \[P\] at \[O\]

• A different electric dipole moment \[p\]

Answer 1

Each position of \[Q\] has its own direction of magnetic moment \[m_Q\]. That direction is compared with the magnetic field of \[P\] to determine equilibrium.
