What is declination?

A magnet is pointing towards geographic north at a place where horizontal component of earth's magnetic field is 40 mu T . Magnetic dipole moment of the bar magnet is 60 Am^(2) and torque acting on the magnet is 1.2 xx 10^(-3) N m . What is declination at this place ?

A compass needle whose magnetic moment is 60Am^2 points geographic north at a certain place where H=40muT . The compass needle experience a torque of 1*2xx10^-3N-m . What is the declination at the place?

A compass needle of magnetic moment 50 Am^2 experiences a torque of 1.3 xx 10^(-3) Nm when pointing towards geographical north at a certain place where horizontal component of Earth's magnetic field is 30 mu Wb//m^2 . What is the declination of the place?

A compass needle whose magnetic moment is 60Am^2 pointing geographic north at a certain place where horizontal component of earth's magnetic field is 40muWb//m^2 experiences a torque of 1*2xx10^-3Nm . What is the declination of the place?

A compass needle whose magnetic moment is 60Am^2 pointing geograhic north at a certain place, where the horizontal component of earth's magnetic field is 40muWbm^-2 experiences a torque 1*2xx10^-3Nm . What is the declination of the place?
