A copper rod moves parallel to the horizontal direction. The induced emf developed across its ends due earth's magnetic field will be maximum at the

At the poles of the copper rod the earth’s magnetic field will be more. This is explained with the help of Lorentz force where he explains that the magnetic field is generated due to movement of charges.

Earth’s magnetic field is defined as the magnetic dipole which is similar to bar magnet and is tilted 11° from the earth’s axis of rotation.
