A magnet makes an angle of `45^@` with the horizontal in a vertical plane making an angle of `30^@` with the magnetic meridian. Find the true value of the dip angle at that place.

The angle of dip at a place is delta . If the dip is measured in a plane makinng an angle theta with the magnetic merdian, the apparent angle of dip delta_(1) will be

Write the values of Bv and angle of dip at equator?

At magnetic poles of earth, angle of dip is

A short bar magnet is placed in an external magnetic field of 700 gauss. When its axis makes an angle of 30^@ with the external magnetic field, it experiences a torque of 0.014Nm. Find the magnetic moment of the magnet and the work done in moving it from the most stable to most unstable position.

Choose the corect options. The horizontal and vertical components of magnetic field of the Earth are same at some place on the surface of the Earth. The magnetic dip angle at this place will be:

The angle between the magnetic meridian and geographical meridian is called

If theta_1 and theta_2 be the apparent angles of dip observed in two vertical planes at right angles to each other, then the true angle of dip theta is given by
