Define magnetic inclination or angle of dip.
Important Questions on Magnetism and Matter
Answer the following question:
Magnetic field lines are always nearly normal to the surface of a ferromagnet at every point. (This fact is analogous to the static electric field lines being normal to the surface of a conductor at every point.) Why?
Answer the following question.
Would the maximum possible magnetization of a paramagnetic sample be of the same order of magnitude as the magnetization of a ferromagnet?
A compass needle free to turn in a horizontal plane is placed at the centre of circular coil of turns and radius . The coil is in a vertical plane making an angle of with the magnetic meridian. When the current in the coil is , the needle points west to east. Determine the horizontal component of the Earth's magnetic field at the location.
Next, the current in the coil is reversed and the coil is rotated about its vertical axis by an angle of in the anti clockwise sense looking from above. Predict the direction of the needle. Take the magnetic declination at the places to be zero.
