Dipole not aligned with B field = rotational motion
B field not constant along field direction = translational motion

Why Br2 microwave active?
I don't think it is. Microwave energy levels correspond to rotational modes, and for rotational spectroscopy, a molecule has to have a dipole moment... homonuclear diatomics like Br2 don't, and thus do not exhibit a pure rotational spectrum.
What is the magnetic field on Mercury like?
According to the NASA website, the magnetic field on Mercury has the following characteristics: Dipole field strength: 0.0033 gauss-Rh3 Dipole tilt to rotational axis: 169 degrees Longitude of tilt: 285 degrees (from Mercury I flyby) 115 degrees (from Mercury III flyby) (whereby Rh denotes Mercurian radii, 2,439 km)
What is the significance of electric dipole in a polar molecule when an external electric field is applied?
in magnetic relays
What atmospheric layer acts like a giant magnet and what does it attract?
The Earth's magnetic field is like a magnetic dipole, with one pole near the north pole and the other near the south pole.
What can you infer about magnetic fields and paper?
You can infer nothing about a magnetic field from paper alone, or about paper from a magnetic field. If you put iron filings on a horizontal sheet of paper and put a magnet below the paper, you may be able to visualize the magnetic field of the magnet and thus infer its dipole arrangement.
What is difference between between electric dipole moment and magnetic dipole moment?
Magnetic dipole is due to two poles of magnet. Electric dipole is due to +ve and -ve charges of electric charges.

What is the potential energy of a point magnetic dipole of moment M placed in a uniform magnetic field B?
lU=-mB Metal
Why is magnitude of an electron spin greater than its magnetic moment?
The Spin magnetic moment i approximately the same as the angular magnetic dipole moment. What then do you men by grater magnitude?
In dipole-dipole forces how thermal energy causes the molecules not to have perfect alignment?
Thermal energy increases the rotational or vibrational motion of molecules and because the intermolecules are not strong enough to hold them it changes their position to some extent and the alignment is
What is the significance of electric dipole in a polar molecule when an external electric field is applied?
in magnetic relays
For a loop of current carrying wire in a uniform magnetic field the potential energy is a minimum if the magnetic dipole moment of the loop is?
in the same direction as the field
What has occurred when rocks formed millions of years ago show the location of the magnetic poles at the time of their formation?
Magnetism is a property of certain materials, usually metals, that have an electric dipole on the molecular scale. A dipole is a significant separation between the positive and negative charges in the molecule. Since electrons and protons have spin, and moving electrical charges generate megnetic fields, the dipole generates a net magnetic field. If enough dipoles are oriented in the same direction the body has a net magnetic field. The dipoles can align when sitting in a permanent magnetic field for a long period of time, like underground in the earth's magnetic field.
Why force exerted by a magnetic field on stationary elctric dipole is zero?
The force on a charge by a magnetic field is given by F = Bq v sin@ v - the speed of the charged particle with charge q. B - magnetic field induction in tesla. @ is the angle between the velocity vector and magnetic field vector. As dipole is stationary, the speed of charges is zero. So the force = 0 Hence the result.
What creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields. "A magnetic field can be created with moving charges, such as a current-carrying wire. A magnetic field can also be created by the spin magnetic dipole moment, and by the orbital magnetic dipole moment of an electron within an atom." A magnetic field can be produced by either a permanent magnet, or an electromagnet, the latter requiring suitable energization to function.
How does a microwave heat up water?
The microwaves excite rotational modes in molecules that have an electric dipole. Water molecules have a dipole because oxygen is more electronegative than hydrogen and the molecules are bent (H-O-H angle about 105 degrees).
